I've had a set of brand new nerf bars sitting in my living room, still in the box, for about a month or more now. I bought them because I'm trying to black my truck out, and I want to get rid of the chrome ones that came on the truck when I bought it. I haven't put them on yet because they're more matte black rather than glossy. I was giving some thought to getting a gloss clear coat that I could use to paint over the black and not only protect the running boards from rusting but also give them more of a gloss look. Does any one have any opinions on this as far as pros/cons go?
