Hambiskit---will do, if I find it. I think I read about it in a 70s era Rod Action or Street Rodder. In the story I read, they used it to make a solid pattern of a curved windshield, and were then cutting it down to fit a car with a chopped top, rather than taking "learn as you go" cuts on the actual windshield.----and yes Hambiskit, I did build all the cars I talk about.
