yes krylon fusion paint works great. just sand the plastics a little bit first to get the big guages out and scrapes out then clean it off with some paint thinner to get dirt and oils off and spray on light layers. its better to put on alot of layers then to spray it on thick and have the paint run. after that let it dry for a couple days maybe even a week before you uses them so it hardens and bonds good. if you do it right it will look like a brand new fender wont even be able to tell there painted and the stuff last for ever with out flaking. you can even power wash it good luck
