So I have a few of these plastic parts on my car which have a chrome like finish...which I have absolutely no idea how they do that...anyways, my car is 20 years old now, and these pieces have scratches, and little tiny bumps on them...and discolored dots, and such, and I was wondering if there's some way to remove all of these. to make it look like new again? I know better than to put Scratch X to get rid of scratches, I tryed that on one of my interior vents, and that took the chrome right off ...oops...lol. I also have some interior pieces, like my vent, where the chrome...whatever it is...has worn off completely over time...to reveal the yellow plastic underneath, and would like to know if there's some way I can put it back. Is it some sort of special paint or somthing I could buy? I'd love to know. Any tips about this chrome plastic stuff would be great! Thanks.
