This product claims to restore plastic but after 10 minutes of scrubbing one headlight cover with it and a terry cloth (as recommended), there was hardly any noticeable difference. I do some bodybuilding so strength of pressure application is not the problem! There are better products out there but I don't know if I'm allowed to mention a competitor's name lest someone think I work for them (I don't)--it's Novus' 3-step system!
