Yeah, my headlights have not turned out exactly the way I wanted them, but the bi-xenon modules are soo HUGE - especially WITH the igniter/bulb holder - that it really messed up my design ideas and forced me to just deal with what I had.
It's going good though and my next set should turn out much better.
The sanding turned out really well, and if it wasn't for the UV stained lenses they would have been clear. They were too yellow to even be worth it, but I had to deal with those.
I wet sanded them. Every grit I used was wet sanded and I just started at 80, then 150, 220, 300, 410, 600, 800, and then 1500.
I spent about 20 mins on each one. A little over-kill, but I had the time and I was REALLY bored. You should expect some blisters though!!!
After that, I wiped them off, and polished them with a plastic polish.
