Received question about sculpting: spray foam from a can better than sheets?

Someone PM'd me this question. I have very littl experience shaping foam, and I know others have more, so I'm posting it here for the group:

Found your post from awhile back, contemplating use of spray foam from a can like Home Depot sells.

How'd it work out? Easy to work with? Dimensionally stable? Smooth and paintable?

I want to sculpt a car nose out of foam, trying to decide which foam, and whether to start with a big chunk and carve down, or use a form and build up.

I've read that polyurethane foam (Great Stuff, etc.) from a spray can is not as good as sheets of polyurethane already cured.

Any thoughts based on your experience would be much appreciated.

Thanks!
