Hey, I got a 2x3 piece of pretty hardy styrofoam from work, and I'm hoping to turn it into a wall for my WD to chill hard on. I need to know, what can I do to give the foam a climbable, and more importantly, safe place for the lizard to climb. If I remember back from a high school class I took, normal spray-paint will almost eat away the foam. I don't know which way to approach this. I know zetec7 has something around what I'm looking for. Thanks!
