The nice thing about Goo Gone is that is doesn't evaporate quickly like acetone so you have more working time. It's also easier on the gelcoat. I had the glue-in-the-non-skid problem and Goo Gone, a stiff brush (plastic bristles) and some scrubbing got it all out. WD-40 and all similar products work pretty well too.
The glue is basically rubber cement, and the solvent for that is naphtha, similar to benzene. Higher fraction solvents (like acetone) may be overkill since any kind of oil eventually softens it up. Mayonaise and peanut butter are recommended because they'll stick long enough to let the oil absorb and soften the residue up, then wipe clean without harming the fiberglass or paint.
The specialty products like 3M's adhesive remover and goo-gone are great, a bit pricey but they work fast and clean if you want to run out and buy them.
