PPF FAQs

Paint Protection Film FAQs

  • What is PPF?

    Paint Protection Film is a Thermoplastic Polyurethane material that offers great protective properties including rock chip and abrasion resistance. TPU films were originally introduced by the military to provide protection for helicopter blades during takeoff and landing. TPU films have come a long way. If you remember paint protection film from 30 years ago, it was unsightly with orange peel texture, easily stained and would turn yellow after only a short time. Modern TPU films are clear and smooth.  DYNOshield is the product we use and has HYDROphobe technology, this is a nano coating infused into the film that not only provides self healing properties against light wash marks but also is super easy to clean with it’s hydrophobic properties.

  • Self Healing PPF?

    During the manufacturing process of STEK DYNOshield, a liquid topcoat is applied that is self healing. This does not self heal if it’s hit by a rock and it punctures, this is for light wash marks.  Self healing happens most quickly when some level of heat is applied, but sitting outside in the sun will provide the same effects.  

  • Why would I have PPF applied on my car?

    PPF provides a barrier of protection that can take a lot of abuse.  Most importantly, it is designed to protect paint against rock chip damage and debris that can damage the paint or clearcoat.  Due to stringent EPA regulations, all new cars are painted with eco friendly water borne paint.  Although better for the environment, it's a much more delicate finish than the paint of yesteryears.  An added benefit of STEK DYNOshield is that it has a self healing topcoat, is extremely hydrophobic, stain resistant and non yellowing.  There is no better way to protect your vehicle’s paint against damage than PPF.  Instead of removing a thin layer of clearcoat every time your vehicle’s paint needs to be polished to remove swirl marks and scratches, we believe it’s best to just add film to your vehicle’s clearcoat when it’s brand new.  The most clearcoat your vehicle will ever have is when it’s brand new!

  • Do people cover their whole vehicles in PPF?

    You bet, in fact we have completed hundreds of full vehicle wraps as it’s the very best protection available today. There are several areas that we believe are the most susceptible to rock damage, this is typically the front end, the lower rocker panels and the rear bumper.  Any area that is in the line of fire from debris kicked up from your vehicle’s tires is considered high impact areas. If you want any more than the high impact areas, we recommend a full body wrap. This will fully take advantage of the film’s self healing and hydrophobic properties and you’ll probably end up wrapping every car you ever buy after owning a fully wrapped vehicle as the maintenance is so much easier than paint.


  • My car isn't new, can I still install PPF?

    Paint protection film can be installed on pretty much any vehicle at any time. To get the most value out of the product, we recommend installing it when the vehicle is brand new. Rock chips and damage under the film will appear as an air bubble and will look somewhat unsightly. Touch up paint can be done under certain circumstances, but it is no substitution for a professional refinish from a qualified body shop. We will ask to look over your vehicle if it has more than a few thousand miles to verify that it’s a good candidate for PPF. If you have a highly sought after or collectible type of vehicle and you want to preserve the original finish and prevent new chips from happening, this is a situation where PPF may still be a good option even though it won’t look like a fresh paint job. We feel this is a case by case basis, please contact us if you would like us to evaluate your vehicle’s paint for PPF.

  • Is PPF removable?

    Yes, paint protection film can generally be removed without damage. There are a few circumstances where this is not the case.  If you have original paint on your vehicle, TYPICALLY the prepwork of the paint has been done properly and can be removed without damage. If your PPF was installed by a unqualified technician with a heavy handed blade, paint can be cut through the film, this will compromise the integrity of the paint and once removed can peel paint away during the removal process. We recommend to check out your potential installer’s 


  • Will my car need paint correction before PPF is installed?

    The short answer is NO. Unless if wetsanding, touch up paint or major defect removal are needed, you can expect that we won’t surprise you with any additional prep fees.  Our prepwork is extremely comprehensive so you can expect to get your car back cleaner than when you brought it in!
