A friend of mine had a clear film material professionally installed on the nose, hood, side mirrors and around the fender wells of his 03 convertible. The problem is he film is all scratched up and looks horrible. Has any one had any experience removing this stuff? Is there a trick to doing it? Will removing it do more harm than good? will the finish look noticeably different than the parts of the car that were not covered by the film?Thanks for your help.
