I got the CMA polishing kit and it worked fine. It's sort of hard to control the little pad on a drill, though. But it worked well. That Renovo stuff doesn't smell that great, but the headlights look much better. It got rid of the haze, but all the little divots and dings are still there (as I would expect). Plus, it comes with a Viper glass cleaning MF and some Plexus. I thought that was kind of nice because those I can use all the time. The polish I hopefully won't need to use again.
