I have a couple questions on Wet Sanding. I just got my taillights and 3rd brake light done,and I was woundering on proper procedure on wet sanding?,I have the wet paper to do it,just want to double check on exactly on how to do it,I don't want to ruin the work I have done,Do you just wet them down and sand them lightly then your done? Or do you have to polished them with plastic polish after sanding?
