In theory, I use the pre-strech and shrink method shown on the WIR video on almost anything?

Almost anything defined as hood, door, quarter panel Answer: The simple answer is no. Pre-stretch and shrink is only applicable to 3D shapes. Mirrors, handles, bumpers, etc. The technique is specific to heating and stretching the film 10-40%, cooling the film, applying and then shrinking out the rest of the app. For flat panels, pre-stretch is not advisable. But, pre-tension is. Pre-tension is typically a cold or barely warmed stretch 2-5% that helps edges want to suck themselves around on certain shapes when executed properly. Our best practice is advisement is only stretch when needed. Apply flat areas with stress free film.
