I thought everyone did it?! I've been using my HVLP spray gun for house painting ever since I got it. Works great. Put in your paint stretch the airhose from the garage or put wheels on your compressor. Hook that sucker up and a 20'x25'x10' room you can spray in about 45 minutes including masking, refills and you don't even need a ladder. My bro used his gun and a jar of rainbow metallic to paint the ceiling in his daughters room, looked really cool. He doesn't use spackle anymore, he uses my frikin body filler. His wife uses my buffer to clean the tub...puts a garbage bag over it uses some liquid cleaning stuff and an old pad and goes to town. Little tip, if you get caught doing this you will get 15 minutes of screaming and just all out hell, but if you come home and they are doing the same thing, don't even think about saying a word. Its hazardess to your health.
