I did 3 very light coats of black spray paint
then I took 300 grit sand paper, hit it real quick
put some Wd 40 on a rag, whipped them off real quick…this gave them the “shiny” look…then for my reverse lights I just sanded that down, then wd 40 again over that part only until all the paint was off that section…
then just a layer of wax and that was about 8 months ago and they still look the same and shiny…not a “dull” look like most do.
