Cheap Headlight Buffing/Restoration... 3 vehicles (can do many more!) for $10-$15 

I wanted to clean up the headlights on some of the vehicles I work on but I didn't want to spend a bunch of money on kits. I settled on a cheap buffer and polish combo to do what I could.
After driving the Rio with one headlight polished I noticed a brighter and whiter beam so I guess it worked.
It didn't show up all that well on camera, but I noticed a visible difference on all the cars and I still have plenty of compound for many more headlights or whatever else I want to use it on.
