I bought aftermarket exterior door handles for my truck. They were shiny black plastic. I scuffed them with 1000 grit paper and painted them matte with this and they look fantastic. I'll come back and update this review and let you know how it holds up. (Today's 10/31/2025).ONE THING THOUGH - It looks like I'm the only one who's ever read the warning on the can - and JEEE ZUZ. "Not for sale to the general public" (nice QC, Amazon!) "Contaminated clothing must not be allowed out of the workspace." "If inhaled: remove the victim to fresh air ..." VICTIM?? "Store locked up." The fumes of this stuff are POWERFUL and LASTING - DAYS after the work is removed from the area. Wear gloves and a mask and work outdoors.
