Hahaha thanks man! When I started doing this I had to go to the junkyard and get a few crap headlights and practice on them, it took a couple sets to really get the feel for it and to get a technique going. Sometimes I would have questions about how to do something so I would Google it, and I was amazed at how many people were misinformed on just about every aspect of what really turns out to be a very simple and logical process.
I just recently got a 3" random orbital and it made a world of difference, it's much easier to control than my Makita cordless drill was, and it doesn't heat up as much so it's not so easy to burn the lens.
