Don't shoot me, I have already posted this in a few marine forums without success. I removed the 14 year old COCKPIT/OUTSIDE snap down carpet from my boat. The backing has rotted out and there is almost none left on the carpet itself. Some of it appears to have baked into the texture tread fiberglass floor. I have tried pressure washing, stiff bristle brush, WD40, and goof off. The only thing working is using a small flat screwdriver and digging it out of the texture. Any idea if I an use some type of solvent to dissolve or soften it so it comes off?
