Now do they make something that will remove 20 year old dried contact cement off the side of a Pacman cab that still has graphics on it (albiet damaged). I pulled off the formica sides (it was converted to Arkanoid) and now am left with a rough, "pilly" surface of pink contact cement. Everything I tried either does nothing to it, or also eats into the paint. Only thing that sorta worked was a random orbital sander with a totally used-up pad... using heat and motion to rub it off.. but that would take days to get it all off!
I too had a problem with this, I wound up using Gasoline

. It really worked the best, BUT IT IS VERY VERY DANGEROUS ON MANY LEVELS!!! (toxic, skin irritent, eye irritent, VERY FLAMABLE)
I even tryed to sand it off, but I only wore out like 50 sheets of san paper and got nowhere. I tryed rubbing alcohol, nailpolish remover, and everything else under the sun. I even tryed this stuff made for this purpose (called txt-be-gone) it didn't even work! This was heavy duty stuff.
Picture me and my brother in my garage, right when I started this project; garbage bags covering our hands (gasoline messes up skin well) with rags wet down with Gasoline rubbing furiosly on this machine, until the point of complete exaustion. Damn that was hard stuff!
