Oil base paint or latex based paint should come off with strong solutions of mineral spirits and washing with dishwashing detergent. However lacquer based or enamel based paints will come off with a solution of lacquer thinner and automatic trans fluid mixed together . The oil cuts the thinner and doesn't soften the orig paint . Try different portions of thinner to oil until it breaks the paint and doesn't soften the orig clear. However looking at the pic I hope it isn't lacquer or enamel based because in that quantity the thinners in the paint have already melted into the orig clear thus creating a bigger ptoblem of stripping, sanding etc. major paint proceedures JMO Best of Luck
