Take the foam off...did I mention...take the foam off...I haven't used a foam bottomed board for, well all I can remember is that when I originally bought one, and one only, after a couple of uses, I took the foam off. Just clean the glue residue off with thinner and You have a usable tool. So many of these tools are preference and all I trying to convey is my preference. I' sure some people may disagree and that is within their right. This is what works for me.
