Air Compressor Size Question, How big is big enough? Options

[BeatNavy]

This may have been covered before, but I did not find it answered explicitly:

What size air compressor is good enough for doing a decent quality paint job on our cars and otherwise work with air tools? I don't have one now, but I am thinking of making the plunge and trying to paint my car at some point. I don't think I would really do anything bigger than a 914.

Here's a more specific question: is a 60 gallon, 3HP, 11.5 CFM at 40 psi; 10.2 CFM at 90 psi good for this? There's one on CL not far from me that could be a decent deal and serve as my post-Christmas gift to myself.

I think what you mention in the original post will work well.

One of my jobs is in guitar manufacturing and we run an Ingersoll compressor about 15hrs a day for Paint mostly. Some sanding and occasionally sandblasting car parts for me.

The name of the game is CFM. You can have a big ass tank and a high PSI rating, but if it can't continue to produce that PSI rating, you're toast. We learned that the hard way!
