I just came across a great expose on one way that companies like Xpel get their templates for precut paint protection film. At first it seemed like a low-tech, labor-intensive way to go about it but the more I think about it the more I realize it couldn't be any other way. Check out my quick summary here and there is a link in the blog post to the complete expose on the TintDude form: http://blog.rvinyl.c...recut-ppf-kits/
Enjoy!
