Yesterday I experimented with a vinyl top on my '68 Camaro project. After MUCH searching on other forums/websites, I came upon Steven Guthmiller (? Spelling, sorry if I butcher it!) procedure for them and tried it.
I like to think I got it just right, the glare doesn't help, but in person it looks pretty dang good.
Then I did it again for the original project that started the search for it, a 1970 Super Bee for a friend.
