MM: Thanks for your reply. I assume you're referring to Sintra, Gatorfoam and Komatex. Are any acceptable surfaces without paint? If not, what paint would you recommend? Gatorfoam is a no no with my kids since it'll dent too easily. Right now I have a painted (Silver Screen) wall with a frame around it. Works fine until the handprints and dings accumulate. That's why I like the idea of a laminated surface.
