This thread is waay off track! @Buzzlightyear all you need is a 12 volt pump. Haven’t you ever heard of an HVLP sprayer? Painters should have learned to use 12 volts years ago. I repainted a house just yesterday with a 12 volt, and I’m sure the homeowner will be happy to see it when he gets home.
I’ll post a picture of the house shortly.
(Only problem is that, since the 12 volts aren’t “designed” for paint, you have to change them out after every 2-3 gallons of paint, or take the head off and replace the diaphragm with dolphin skin one, which lets you pump about 5 gallons before it’s toast… It’s kind of a hassle, but it still saved me almost $23.00 over hiring a “professional” painter)
