I have a 92 xlt and I want to paint the grill and bumpers black like the 92 sports. Eventually I will replace the dog leg and get it rhino lined from the trim down in black also, to look like the sport. What type of paint should I use for the bumper and grill and what type of prep should I do to these parts(bumpers and grills? Also, does the plastic insert in the bumpers come off?
