It's called "Great Stuff", and there is nothing great about it. The chemical is Diisobutyl phthalate, and it is nasty stuff that offgasses.
Damn I never knew that. Is there any other solutions rather than taking it off, I'm guessing a few heavy coats of paint would do jack?
I got a very bad virus, it really kicked my ass but I'm better now, thanks for the heads up.
PS the foam is in my mom/clone area and they are looking fine.
