First of all youll need a few things:
1.) Various sandpaper grits. (400,600,800,1500)
2.) High gloss clear coat. It needs to be uv rated so it wont yellow over time.
3.) Some paper towels
4.) A Tupperware container of water for wet sanding
I started off slow using a coarse grit sandpaper to remove any yellowing.
After the yellowing was pretty much gone i worked my way down to wet sanding with fine grit sandpaper. After getting the light nice and smooth, i prepped the light for the clear coat by wiping away the plastic headlight dust.
I ended up letting the clear coat dry, then sanding lightly again to apply a second layer of clear coat. Keep in mind this was just a quick and dirty version. Im sure the results will be better with more sanding/ clear coat. The final results:
