Foam is sweet stuff. I have TONS of this stuff at my shop in 15 and 18 lb density. Its known as HDU or High Density Urethane in my business. Never even thought of using this stuff for a bezel but after thinking about it, this would work well. Not for structure though, just as trim. When you go thin it gets brittle and will crack if enough pressure is applied to it. But for trim work its almost a perfect solution, Great Idea man!!
