Yeah . . . I've researched and you are correct, that darn protective film goes yellow after years of beating from the sun and elements. I'm a really handy guy but for some reason, the resto kits scare me. I'd hate to scratch the heck out of the plastic and am left with my screw up and need to drop some serious change for new units.

Guess I'll get the kit and try it on a friend's car and if it works well, I'll do it on mine.
