I have mine tinted but seeing as I have the 3d tails.. I left the reverse clear with LED reverse lights... And also have a 60" light bar with breaks, turns and white reverse lights.. So everyone knows what I am doing.
I reconmend a light wetsand first... good cleaning, nightshade to preference of shade.. several coats of clear, light wetsand if any imperfections.. Then make sure to polish them with the assistance of elbow grease and then wax em. I have done several sets including a second set of mine after someone smashed my first set
... Works great.
