try POR Strip its made by the POR15 people. incase you didnt connect the names...I have used it...its great stuff. just need to be careful with it. it smells bad and stings if you get it on your skin. and the taste is well....ok I never tasted it...you just spray it on and in a few minutes scrape it off. the best part is its fast and it dries up and you can sweep the dust up off your garage floor. not all goo like some other strippers...paint strippers.....
