I have to agree with Harrellbenjamin, I used air tools when I worked in the body shop trade, they are light and easy to use and give you much better control of the job you are doing, they are also easier on the users back, Dragging an air hose around is no more hassle than an electric cord, Electric tools are heavy by comparison, Even so electric seems the easiest for most mobile guys, its not like headlights are a big sanding job compared to body panels.


To answer your question Brent, there is no real answer, Some air buffers/sanders use more CFM than others, so you really have to know how much CFM your tools need, then buy and air compressor that will keep up with that, buy one that is too small and you will waste time waiting for the compressor to build up, plus the pressure will be affected too, Compressors are sold on the size of horsepower of motor which is a bit deceiving, Pressure and CFM ratings are the most important.

This takes me back to the post I had about a Grex orbital sander, I found that item on Amazon, it said the sander only needed 2.2 CFM @ 90psi, I thought that was a very small amount of air seeing as many other buffers I see run on 12-13 CFM @90psi, after a while someone on another forum told me the Grex uses around 8-9 CFM @ 90psi... 2.2 CFM would have been great, but its seems to be an error, it also has a 2 inch head which would be great for tight spaces.
