Who has recommendations for inline filters on the air compressor, for
water and other stuff? And sources?

thanks

I second the tool lubricator. You definitely need a water filter (sump)
and need to drain the air tank periodically, or it will corrode and can
result in a nasty explosion.

A friend was painting a new RV-8 and was getting fisheye, even though he
had cleaned everything. I suggested that his air supply was contaminated
(it was) and was putting out droplets of oil alnoh with the paint.

He cleaned wverything up and got a nice finish.
