Let me preface this post by saying that I work for a urethane film manufacturer. I'll try to keep all bias out and stick to the facts.
Here's a few things everyone should know about paint protection film before purchasing a clear bra:
1. The film you choose matters! Do your research on films in advance, as they are NOT all the same, regardless of how similar they look initially. Different films have different surface textures (or lack thereof), as well as widely varying resistance to scratches, yellowing, haziness, and chemicals. Some films can be scrubbed with lacquer thinner, while others will haze up with the use of common paint care products (synthetic waxes often contain petroleum distillates). Some films heal their own scratches, while others require buffing. SOme films require specific maintenance to maintain there appearance, while others can virtually be lef alone.
2. Find the right installer! A good installer can make virtually any film look good, while the best film in the world can't make an inexperienced installer's work look top notch. A large portion of the cost is due to the labor involved. Just like when you go to a doctor for a 10 minute visit, you're not paying him/her for the 10 minutes of time as much as you are for their expertise and the training it took them to get there.
3. Check with the manufacturer for recommended care intstructions. As I mentioned before the clear coats on these films vary greatly. Check with your manufacturer to make sure that none of the paint products you use are harmful to the urethane (it is best to stick with all-natural waxes).
4. Ask for different coverage options to fit your budget. With the ability to customize coverage, installers have the ability to custom tailor your job to fit your budget better than ever before.
Clear bra is only a good investment if you use a quality film and have the job done right. It is not worth it to save a few bucks, if the installer is not experienced or using a top-notch product, as it will only turn out as an eyesore. Take the time to do the research, and it will be something that adds to the value and the aesthetics of your car.
