The powdercoat on my Mopar bumper has already got rust around the welds and a few chips on it, so I wanted to coat it or paint it with something to make it look new again. The problem is, I can't find any information about how to prep an already rough textured powdercoated surface. There is lots of information about sanding a smooth powdercoat or painted surface to make it rough, but my powdercoat is already rough/gritty textured. Does that mean I just have to clean it, and I don't have to sand it (since it already has a gritty texture)?

I was looking at Linex, or attempting the DIY version with Duplicolor bedliner spray. Does anybody have experience with touching up or repainting a textured powdercoated bumper?

 

Just make sure its clean and then go right over it with bedliner. It sticks like crazy and looks great

 

Biggy, what kind of bedliner did you use?

 

i know im not biggy but i used rustolem bedliner for my grill...some guys use duplicolor but i couldnt find it at autozone
