you can try gasoline and a putty knife.....but i heard that conventional pump gas has a chemical that breaks down fiberglass resin and to use camping gas instead. i have not tried camping gas.
i stripped my floors clean using a variety of things like a DA sander, angle grinder with a wire wheel....where its thick, it will gum up a lot. it would then be warm enough to scrape it out with a putty knife.
oh yeah....you will need LOTS of elbow grease....that stuff does NOT come out easy.
