I use a sheet rock blade it's 6 inches but very sharp and a mallet.. I was able to get them off in one piece. Once you get it going you can slice away at the glue. No heat or solvents. Once all peeled use laq thinner let set for few mins and rolls right off with your bare hand. Never use mineral spirits glue will not stick ... The spirits never dry for a long time. Heat gun does work well but left it on a job.... My whole problem is going to be drilling the Formica once installed. And getting the sights flush.. I'm going to use a cobalt bit with a 1/8th inch stop.. Well see how it works... I went with Matt black Formica.. Never wear out....we need to make a sight that is installed from under rail with a adjustable hight screw for flushness....drill where you need it to bee and then sight is installed under with set screw.... Done... No more flush problems..... Stay tuned I'll have to make a part number...heheheeh
