You can take the paint off if you submerse the parts in lacquer thinner, I have found some guns flake off quick and others need to be blasted. But I hate to burst your bubble but the park job underneath is pretty terrible. They do not blast them before parking so you get a piss poor blotchy park job that is thin. The best way is to remove it all and get a fresh start. There is a alot of shortcuts taken on these guns, even the mags, they are not even blasted before being painted, hence why they flake like crazy.
