oiless compressors run HOT. HOT= major moisture problems.

I have a small water separator at the gun and have this at the compressor:

The blue desiccant beads do turn pink after each day of spraying so I make sure to start with blue beads. Not good enough to remove most moisture? I am only planning on spraying primer (poly first and then urethane). I am not going to spray the base or clear, bringing the car to the pros for that.

Your getting way to much water! you need a water trap.
Your Desiccant filter is the last step in filtering, it should last a very long time between drying it or replacing it.
I have had mine for over a decade and only ever dried my media once and I have never replaced it, its always nice and Blue.
