I wouldn't do it. While the Mop & Glo will clean plastic, it is a strong solvent and may dull the finish. I've used it many times on my ZX14, but if you're going to apply a clear coat afterwards you could jeopardize it. I've never used Mop & Glo on my plastic, but I do use regular dish soap and water with a soft rag. I've never had a problem with it. I've heard of guys using ArmorAll, but I don't think the stuff is good for the plastic. Just my opinion.
