We laugh, but I have friend with about a 1993 Maroon Corvette that might even be the 40th Anniversary model, don't remember.
Anyway, the car always looks great and has never had anything on the paint but some off the shelf product in a light green bottle. I think it's called Finish 2001 or something close to that. It might even be a Turtle Wax product. The car isn't subjected to the elements, but even so, I was totally amazed. I didn't check the paint up close, but walking by it, it looks pretty darn good.
:dunno
