I have 4 of the round chrome plated offroad lights like the ones you can get from summit racing. They were given to me by a friend who had them sitting in her barn and out in the weather for a while so they got all rusty looking. I am going for the all black accessories for my truck. Here is the million dollar question, will truck bed coating or truck under coating stick to them if i rough them up REALLY good? So far I have gotten 2 answers. If so then that will be my weekend project, if not then I will have to buy new lights and thosewill sit in a box.
