On the subject of drill-based detailing, next project is to clean up the headlights. I've used 3M's Plastic Clean and Polish by hand in the past, but this time I picked up 3M's professional cleaning kit that includes super-fine grit sandpaper, foam applicator pad, etc. all of which attach to your drill.
We'll see how it goes. If I can get to it this weekend (looks like Tropical Storm Danny may rain us out) I'll post before and after pics of that too.
