I have a small air compressor.  I want to attempt cerekoting a stripped lower.  Can anyone recommend the latest paint guns used for this?

This video might help. Although not sure how small of an air compressor you have.

I agree, the paint guns need to be matched to the air flow available. If you have a little airbrush compressor you are limited to what it will continuously put out. I use a medium sized Craftsman air compressor, and usually let it build to full pressure, then shut the noisy thing off and paint with the air in the tank, regulated to what I'm working on. I would do it differently if I were painting a car, or something larger of course...
