i want to recover my airplane but how do i remove the old "stick on" covering ?? i`ve taken the easy to remove stuff off. but what about the stubborn stuff? there`s also alot of the glue left on where the fuel was on the covering. i tried a iron but that didn`t work. is there a chemical that will remove the glue ? i tried alcohol with no luck. how about acetone or laquer thinner? thanks alot conk
