THe black silicon is pretty easy to scrape off. One word of warning is that the foam begins to fade over time, especially if it is above the waterline. The black will turn to more of a purple color, and the white turns yellow (all due to exposure to light). <HR></BLOCKQUOTE>
I think that's typically why these foam sculpted backgrounds get covered in colored resin. That and to give the soft foam surface some protective coating.
