5 Things to Know Before Buying Windshield Film

Windshield protection film has taken the automotive restyling world by storm. While paint protection film and ceramic coatings are pretty much old news, windshield protection is probably the latest new product to hit the shelves of your favorite local tint shop.

Even if you’ve already heard of windshield protection, you may be wondering if it’s really for you, or if it only really makes sense for supercar owners. In this post, we’re going to break down who windshield protection film is really for (and no, it’s not everyone!), what it will (or won’t) protect against, the best time to purchase windshield protection, and where to get it!

What is Windshield Protection Film?

First of all, let’s clear up a few common misconceptions about products to protect your windshield.

If you’re looking for something that will actually protect your windshield from rock chips or other damage to your glass, you’ll want to look for a clear, impact resistant film that is applied on the outside of your windshield.

Unlike coatings or other surface treatments that installers may apply on your glass, a protective film is really the only thing that will actually protect your windshield from impact.

How it Works:

When a rock or other debris from the road hits your windshield, the film will absorb the force of that impact and distribute it across the film, rather than to your windshield. Not only does this prevent small chips or cracks that happen when a mid-sized rock hits the glass, but it will also prevent the glass from getting scratched and pitted over time from the tiny stones or sand that is pretty much constantly bombarding your windshield.

‍

Who is Windshield Protection Film Made For?

While we have to admit we’re probably biased, we actually don’t believe that windshield protection film is right for everyone! Depending on the vehicle you drive, your insurance policy, and the environment you live in, windshield protection may not be right for you.

You own a supercar, exotic, or rare vehicle

If you’re driving something that most people would only dream of even getting to ride in one day - you probably need windshield protection. Even though the glass itself may not be significantly higher quality than your middle-of-the-road commuter car, with an expensive car comes expensive maintenance - including the windshield.

When your windshield is in the $+ price bracket, protecting it is really a no brainer. You’re probably also protecting other surfaces of your vehicle like the paint, so bundling in windshield protection is a great option.

You have a hard-to-find windshield

Even if you don’t drive your dream car (yet), if your car has a windshield that is difficult to replace, it’s extra important to take the necessary steps to protect it - otherwise it could mean unwanted time off the road.

While there’s no rule of thumb, generally if you drive vehicles that are less popular or a little older, the windshield may be more difficult to find (especially if you’re a stickler for only OEM parts). This can also apply if you’re driving a classic car where finding parts for it in general requires a small miracle.

If you’re not sure if your windshield is readily available, we’d suggest giving a couple local glass shops a call or crawling through various online forums and reddit to find out if people have had bad experiences in the past.

You spend a lot of time highway driving

Commuter vehicles are some of the most likely to have to face frequent windshield replacements because of the horrendous highway roads and the number of transport trucks that you’re stuck behind on a daily basis.

And while you may be thinking “My car isn’t worth $100k, so my windshield replacement will be affordable”…think again! Windshield replacement for almost every modern vehicle on the road is at least $ or more in because of the technology behind the windshield that powers features like lane-keeping assist or collision avoidance.

Again, checking in with your local glass repair guy, scouring the internet for more information, or using an online quote calculator tool will give you an estimate for what you can expect.

If this is you, windshield protection will give you that peace of mind when you're on the road every single day.

Your roads are terrible

If you live somewhere like this, you know it. Some cities are notorious for having terrible roads pretty much year round. There are also certain places farther north that use gravel and dirt on the roads during the winter, which is your windshield’s worst nightmare!

If you’re finding yourself replacing your windshield every year or more, windshield replacement film is a great way to spend a little more time out of a glass repair shop this year! The cost of a windshield protection film is going to be a fraction of the cost you spend on windshields in a year.

If you don’t fall into any of the above categories, that doesn’t mean that windshield protection isn’t right for you! Ultimately there are a few things to consider:
‍
1. How expensive is your windshield to replace?
‍
2. If your windshield costs you $150 to replace, all the more power to you! Unless you’re finding that it breaks a couple times a year, you may prefer to just deal with the regular replacements.

3. How easy is it to get a replacement windshield for your vehicle? How frequently would you have to replace your windshield?

4. What does your insurance cover? If your windshield only breaks once every 5 years and your insurance fully covers the cost - congratulations! We can’t say we’re not jealous, but we’re definitely happy for you.

What Will Windshield Protection Film Protect?

As you can imagine, we get a lot of interesting questions when we tell people that there’s a product out there that can save their glass. While a windshield protection film will give you peace of mind while on the road, it’s important to remember that there are some things that it will NOT protect against. Windshield protection film is not the same as bulletproof glass, and will not protect your windshield from large boulders, hitting a moose, or other (hopefully) once-in-a-lifetime events.

That being said, a windshield protection film like ExoShield protects against chips, cracks, or pitting that comes from small stones hitting the windshield at highway speeds. This means fewer repairs or replacements while you have the film on your windshield.

‍

When to Get Windshield Protection?

The best time to protect your windshield is yesterday.

In all seriousness, like most insurance products or investments, the sooner you get it, the sooner you can reap the rewards! If you’re buying a new car, that’s a great time to do all your protection products at once - windshield protection film, paint protection film, ceramic coatings - etc. As soon as you drive the car off the lot, your windshield will start to get small pitting marks or scuffs that will never go away, so the sooner you get that covered, the better condition your windshield will be in.

If you have damage to your windshield, it’s important to assess the extent of the damage before getting a film like ExoShield installed. If it’s anything more minor or purely cosmetic (scratching, pitting, etc.) you can install the film on your windshield as-is without many issues. While the film will not necessarily improve the appearance of the windshield, it will prevent it from getting any worse.

If you have severe damage or cracks, it’s best to wait until you’ve replaced your windshield to get ExoShield installed.

Where to Buy Windshield Protection Film

There are a couple different ways that you can get protected with a film like ExoShield:

DIY Kits (for select models only)

If you drive a popular off-road vehicle with flat glass, you’re no stranger to broken windshields (we’re looking at you Wrangler owners…). The good news is that there are DIY kits available especially for you through ExoShield. We offer ExoShield ULTRA kits, which have a thicker, more impact resistant windshield protection film that you can install yourself in about 30 minutes in your garage. You can shop DIY kits online, or reach out to your local installer to see if they carry ExoShield ULTRA.

‍

Find a Local Installer

Most of us are all too familiar with that sinking feeling (and the outburst of profanity) that comes right after a rock hits your windshield.

Replacing your windshield is just flat out annoying. You have to spend time finding the right vendor, take hours out of your day to get it replaced, and at the end of it all, end up spending hundreds or thousands on a windshield that can just as easily break again.
‍
If you're here looking for a way to protect your windshield, you can probably relate to at least one of the following:
‍
1. Your passion is your car. When you love something you take care of it. You may already be protecting the body with paint protection film, and now you want to do the same for your windshield.

2. You’re tired of replacing your windshield (we’re looking at you, Jeep owners). Flat windshields like the ones on your Jeep are basically rock-chip magnets and regularly replacing your windshield is expensive and honestly just annoying.

3. Your vehicle has advanced driver assistance features. The sensors powering these systems sit directly behind the windshield and need to be recalibrated when the windshield is replaced (which is usually an expensive and time consuming process). In fact, AAA recently found that the average person can now expect to pay $ or more to replace their windshield.
‍
Over the past 5 years, windshield protection films have become a popular and reliable way to protect your windshield.

What is Windshield Protection Film?

A windshield protection film is a thin film designed to stop rock chips by absorbing the force of impact from rocks, gravel, or other debris. It is applied to the outside of the windshield, and when done right, should be completely invisible. It's like a giant screen protector for your windshield.

‍

How it Works

Glass windshields have an inherent problem – they break easily. Since glass is naturally brittle, it's pretty bad at absorbing impact from things like stones that come flying at it while you're driving.
‍
A windshield protection film works because it’s made of a material that is softer than glass. This means that it does a much better job of absorbing the impact from incoming objects and distributing that force to stop the glass from breaking (within reason of course– a windshield protection film will NOT stop a giant boulder from smashing through your windshield...).

Windshield protection films are usually made up of  three layers:

‍

How to Install Windshield Protection Film:

Unless you’re a trained windshield protection film installer, you won’t want to tackle the installation on your own. If you try to do it yourself you risk burning the film (it needs heat to mould perfectly to the windshield) or worse – scratching or cracking your windshield. Better to leave this one to the experts.

In , most reputable windshield protection films are sold exclusively through certified installers who have been trained to install it perfectly on your vehicle without damaging your windshield or the film.
‍Here's a list of installers we trust.

Choosing the Right Windshield Protection Film

It’s important to think carefully about anything that you’re putting on your windshield since the wrong choice can affect you (and your family's) safety. Low quality films that have poor optical clarity will reduce your visibility (putting you at risk of an accident) and could impact how the sensors behind your windshield perform.

As windshield protection film becomes more popular with drivers, it can be tough to choose from the growing list of options out there. Not only are there multiple brands to choose from, but these brands also use different types of technology which can make it hard to compare.

We want to help you make the best decision to suit your lifestyle. Keep reading for a breakdown of the most common types of windshield protection film.

Scratch Resistant vs Self-healing Films

Most windshield protection films on the market are classified as either scratch-resistant or self-healing films.

Scratch Resistant Films

Scratch resistant films use PET (polyethylene terephthalate) which acts as a soft, shock-absorbing layer. PET is extremely chemically stable and tends to last a long time. The PET is protected by a scratch-resistant topcoat (you might hear it called a 'hardcoat') that stops it from being scratched, prevents UV damage, and adds chemical resistance. A good hardcoat is designed to have what’s called high ‘hardness’ – which means that it won’t easily be scratched, and keeps the film (and your windshield) looking like new for a long time.

Pros of Scratch Resistant Films

• The topcoat of a high quality scratch resistant film creates a very 'hard' surface that makes it extremely resistant to scratches without significantly wearing out over time.
• The PET used in scratch-resistant films is more chemically durable, and will last a lot longer than softer polymers (like the TPU used in self-healing films), giving you a much longer usable lifetime.

Cons of Scratch Resistant Films

• PET is known to degrade when exposed to UV for long periods of time. Fortunately, decades of research has gone into fixing this! Now, the topcoat for most scratch-resistant films includes molecules that absorb the UV radiation before it has a chance to reach the PET layer (make sure to look for this when comparing different brands).
• In some extreme environments, the bond between the topcoat and PET layers can start to weaken, causing the layers of the film to start to separate from each other over time. This is an issue that you'll see with any layered film, and lots of work has gone into finding a solution.

Should you buy a scratch resistant windshield protection film?

Scratch resistant films are extremely durable, making them the most popular choice for windshield protection. Since they first came on the market several years ago, PET-based films have come a long way to get to what they are today, and the technology is still continuing to improve.

A scratch resistant film is right for you if:

• You drive regularly and don't store your car in a garage
• You're doing any off-roading
• You're not washing your car regularly (once a week or more)
• You live in a cold climate
• You expect to face poor road conditions (construction zones, dirt roads, etc.)

Self-healing Films:

Self-healing films use TPU (thermoplastic polyurethane) as the soft, shock-absorbing layer, which is used to make paint protection film (PPF). The TPU layer is covered by what's known as a ‘self-healing’ topcoat. Unlike the topcoat used in scratch-resistant films, the self-healing coating is actually very soft and scratches easily. But it's this softness that gives the coating its self-healing property – when there is a small scratch in the surface, the molecules in the coating will rearrange themselves to fill in the scratch, and the surface of the film looks like new.

It's only recently that self-healing technology has been borrowed from PPF to be used on the windshield and there hasn't been much real-world evidence yet to prove that it can survive the tough environment of the windshield.

Pros of Self-healing Films

• Any minor scratches in the film will be ‘healed’ pretty quickly, and you shouldn’t notice any difference in the film once it has healed itself.
• The self-healing coating bonds really well with TPU because they are made up of similar molecules. Although the layers will eventually separate over time, this strong bond between the topcoat and TPU should reduce the rate of separation.

Cons of Self-healing Films

• Unlike scratch resistant films, self-healing films offer no protection against deep scratches that can be caused by sand trapped in your wiper blades. Any significant scratches in the film's surface will be permanent.
• The self-healing feature will wear out over time, and eventually even minor scratches will be easily visible on the surface. While this is ok for paint protection film where you don't have to worry about wiper blades scratching the surface, you could risk compromising your visibility when it's on the windshield.
• TPU is not as chemically durable as PET. Common glass cleaners and washer fluids can cause the film to discolour or can even weaken the bond between the topcoat and TPU which causes the layers to separate.

Should you buy a self-healing windshield protection film?

Although self-healing technology has been around for PPF for a while, it is just still in the early stages of testing on the windshield. Depending on your driving habits and lifestyle, this may not be a risk you want to take.

A self-healing film is a good option for you if:

• You expect to drive your car only a few times a year
• Your vehicle is stored in a garage year-round

Which technology do we use at ExoShield?

You should be able to rely on your windshield protection film, and we believe that the durability and longer lifespan of scratch resistant films make it the best choice for most vehicles.
‍ This is why we chose to build ExoShield using scratch resistant film technology and spent over 4 years developing our industry-leading nanoceramic hardcoat that protects a layer of shock-absorbing PET. We also use a high-clarity, automotive-grade adhesive that has high strength but can be cleanly removed without leaving any residue on the windshield.

Where to Buy your Windshield Protection Film

Once you choose the windshield protection film that’s right for you, it’s important to find an installer that you can trust to take care of your vehicle. Look for installers who are 'certified' or have done a training course specifically for windshield protection film. We also suggest asking to see examples of work they’ve done in the past – most installers will post photos of their work on instagram – for extra peace of mind.

We certify every single one of our ExoShield installers by putting them through our training program before including them on our reseller map - you can check it out to see if there’s an installer in your area.
