Anyone heard of putting lubricant on the air holes?

That is a thoroughly oiled gun, just like a new gun purchased that you have to clean out before use. They failed to mention in the video that type of "oiling" is done to a spray gun which will be stored and not used for a period of time greater than a week.

The oiling I do on my guns on a regular routine is the needle at the trigger so the needle freely passes through the packing nut, and also on the air cap threads to help reduce galling of the threads from repeated removal of the air cap for cleaning.
 
I have never oiled any of my guns, and in the 45+ years I've been painting, I have never had an issue the oil would have prevented.
 
Back before Teflon packings, I would put a drop on the needle just behind the packing nut and pull the trigger to work it in. This seems to help prevent a sticky needle that could happen from time to time when having the packing adjusted tight enough not to leak air or fluid. But nowadays this does not seem necessary.

I do the the same with gun or mineral oil. I believe mineral oil is the least likely to attack the plastic or rubber seals. That is why they use it on the o-rings in AC systems.
 
What about the removal of the gasket in the air cap? I have yet to hear anyone say to disassemble the air cap before soaking. Is this common knowledge that goes without saying? If so, I'm glad I saw that video but will avoid the lubricant unless preparing the gun for long-term storage.
