My Hummer is black and i have a nice fiberglass painted tire cover, but those damn plastic rear louvers have drove me nuts since day one. Maybe its just me, but i think it cheapens the look of the vehicle so i wanted them painted. I decided to buy a spare set off of ebay incase i dont like how they come out painted but as of now im happy. I painted them with black krlyon fusion paint and used the whole can so its on there pretty thick. If they start chipping or what not ill just put my old ones back on--the louvers where only $10bucks off ebay and the paint was $4 so worst case i throw away $14.
Heres the comparison:
This is not the best picture as it was taken at night but you get the idea. The left is the factory plastic, the right is the krylon fusion black:
I would like for all of my plastic trim peices to be painted including my bumpers, but i guess it wouldnt be practical offroad--would look nice though. Im very curious how Sewell paints the trim on the trucks and honors the warranty--it just seems impossible to warranty the paint on plastic.
