Finally tackled this today. Been on my to do list for almost 2 years.

After:
Have to order the corners to finish it. Also going to go buy a 3" polisher and work on them some more. For now though, they are deambered and I am happy. Particlewave makes it look very easy. It wasn't. It's quite a bit of work, and the whole time I kept thinking, I'm going to ruin a very expensive set of headlights. Glad it came out ok, and grateful for Particlewave's excellent and clear directions.
