So me and my brother tackled most of the undercoating on my car today. There is still small spots and some residue. Is there a chemical to take that off or maybe a wire wheel to finish it up?
So will the paint! LOL. If its just residue mineral spirits or wax and grease remover on a rag cleans it right off. For thicker stuff, chip away with your favorite tool, wire wheel, heat gun all work. And yes it sucks.
