I have an air buffer that I picked uo at harbor freight, it seems that, my 21 gallons air compressor is not enough to keep it running. What is a good electric one that can do the job at from harbor freight?

I use a dewalt 849 but that will run you about $200 , look for a 6" backing plate and 1k- 3k rpm variable speed. I looked on HF's website but not sure what grinder will work with cutting, polish and foam pads for polishing. maybe buy one wool polishing pad and take it with you but again, you dont want anything with fixed speeds.

Paul, I answered this in a post to you a couple of days ago didnt I?

The one I got looks like this,

But mine is yellow I think. It was on sale when I got it for 29 bucks. It's ok for the occasional jobs, work well on my car. I wouldn't use it everyday and expect it to live though.
