I worked on my lenses Sunday, I had the Chrysler kit that included 600 1000 2000 grits sand paper, some oily lubricant for sanding, and some cleaning fluid to get the oily stuff off with and some sealant (seemed like polyurethane to me). I also had a 3m kit that I got at Pep Boys that attached to a drill. It had a 3000 grit polishink pad, I did not use the polishing compound that came with it, I just used water (after going though all of the steps with the Chrysler kit except the polyurethane). Then I urethane'd it. They we OK before the treatment with the urothane. They were pretty bad when I started, and they look fantastic now. I also had a loose cap on one of the driving lights and I fixed that today.
