Thanks Alan,
It says right on the can that it's specificly designed for automotive headliners and vinyl tops. And it says that it's resistant to heat. It's good stuff, easy to work with. Coencidently I found it on one of the links that you posted a few weeks ago. I thank you for that aswell. john.

FYI, I looked up the 3m FoamFast and it says it's not recomended for vinyl.
