I want I paint the plastic fender flares on the TJ but I don’t want them to be shiny, would prefer a rough flat look, kinda like the bed liner look maybe. Here’s how it looks now. I’m not going to paint anything else on the Jeep. Kinda like the old rough look. I want to paint them black. Do I prep (other than cleaning). I’m a newbie at this so I want to make it easy and as cheap as possible. Any suggestions? Thanks
