I just bought a quart of contact cement to try this very thing. I figure the mat is ruined to start with so if it doesn't work I'm not out anything. I have a scrap of plywood and am gonna have friend go around it with his router to smooth out the edges if it works. Maybe I should add this to my long list of weekend chores.
