ADHESION PROMOTER FOR PLASTIC PIECES.
OK remover rear bumper and side skirts, then tape off the front end of truck where the bumper is, and plastic the rest.
SAND all the texture off of the plastic pieces with 80, once they are gone, sand the pieces again with 180 making sure the 80 scratches are out, then 320 it, clean the pieces off with water and soap, then wax and grease remover, spray 2 coats of the adhesion promoter, and primer the pieces, once they have dried, wet sand with 400 grit, and then paint them what ever color you'de like.
pending on how you paint they should come out shiny and smooooooth. and of course the smoothness with depend on how much texture you have sanded off and smoothed.
I did this in a professional shop by myself and it took me a week to get all the texture off.
I sprayed no orange peel/dry spray and all texture is off. looks just like the rest of the truck.
