See previous post on the car that these tails came from. According to the local e30 folks the car had Corvette wheels and was a “rat car” in a good way. Supposedly the engine blew and that’s how it ended up at the auto wreckers.

• washed the lights to remove all the dirt
• wet sanded the lights with 1000, 1500 and 2000 grit
• tails were still pitted (and of course full of small & large cracks)
• sprayed with 4 coats of Rustoleum clear gloss
• sprayed with 2 coats of Testor clear gloss (by far the superior product)

Tails are no longer dull and pitted, now they are shiny and wavy from many layers of clear over crappy paint, probably a solid 4.5 out of 10. I like the way the all-red tail lights look on the car and will probably do it my own tails (but do it right).
