I've got a aluminum boat that I got in the 80's with a Aluminum floor and carpet over that. The carpet is rotten so I removed it but the glue is tough, looks like it was painted on and carpet was laid over it. I got the carpet off and the scraps of carpet but the glue won't budge. I've tried carb cleaner, mineral spirits and automotive bug and tar remover, only the carb cleaner did a thing and it took a lot to get a quarter size spot clean. Does anyone have a solvent that will cut the glue residue so that I don't have to resort to a wire brush or sand paper. Thanks for your help.
