Nice tail lamp. Don't use rubbing compound though, look for polishes made for plastics. I read somewhere that rubbing compound is good for painted surfaces only.
Also if you (like me) hate to see faded amber lenses, look for two-part lacquer paint. Be careful when you're applying it though; too much thinner and it'll melt that gorgeous lens! I didn't spray my lenses with the two-part stuff though, I couldn't find any locally and I was impatient to see it on the car! I used the usual TOA lacquer clear on mine (two coats each).
