I have thought of projects that would involve endless cutting and sanding of foam block, but that should be done easily with Great Stuff, if it just did not shrink.

Jasen, does the marine foam shrink?
I chose plastic wrap because that is all that i had laying around at the time . But that ended up being a bad choice of material because as you can see with grill block v 3.0, the plastic wrap ended up sagging.

Im weary of using wax as a release agent because i dont want to risk not doing it right, then i have globs of resin stuck on my brand new paint. If grill block v 3.1 doesnt turn out right, then i might resort to covering my grill in wax as a release agent.

The yaris with the nicer grill block was CigaR007..which is my inspiration

Like Jasen mentioned, CigaR007 used marine foam for his grill block, the upside to this is that it does not shrink. However, the foam is 2 parts (requires 2 buckets) and you can only purchase the full buckets (a bit overkill for such a small project).

I got futher inspiration to revisit great foam because of Daox's "pretty grill block" thread. I think the key with greatfoam is that after you cut/sand it, you have to resin/fiber glass it right away...otherwise you get the shrinking problem. However, it looks like Daox never got around to finishing his grill block, but it looked good enough for me to revisit great foam
