I guess I am guilty of witholding information the reason I posted the question is because I purchased a almost new machine, yes it works off nitrogen which doesnt react with paints, the bottle is normally about two hundred to get a lease started and it costs between 20 -25 for a exchange the drip problem is solved by stopping spray last six inches then pulling back over line while spraying that six ( sounds like it will always drip to me) will have to see how it works. well gonna read more of your book thanks for doing the research, George
