like denatured alcohol? or like paint thinner? i know i have denatured alcohol around for our granite, but don't think i have any paint thinner. or are talking like acetone? sorry just don't want to have to make another trip to hazordous waste!
second on cosmocat. paint thinner/varsol is one of the best products ever invented. wont damage the paint, but always put some polish on just incase, with any of the products. all depends on how old the gel coat is.
