I've got a bunch of co2 tanks from my paintball years, and I can fill it myself also. That's a good ideaI built mine . Using a longgray 1.5 gal stainless pump up a kleanrite inline quick connect filter 10' hose and gunjet off my hydroforce sprayer and a rechargeable air compressor from Costco. The compressor in in a bag i bought from patriot sprayers. They sell a sprayer that uses a paintball gun co2 bottle to maintain pressure. been using it for yearsno problems even have a dedicated charging port built into my truck to keep it charged i like the patriot sprayers idea of constant pressure but there's no place close for me to recharge the co2 cylinders otherwise i would have bought 1 of them with a spare bottle and modified the hose. A friend of mine stains concrete and uses um and said that the patriot sprayers are expensive but last forever with little or no maintenance . I got about 200.00 in mine

Thanks hope it works for ya. I would like the constant pressure that co2 would allow. As it is now i set the pressure at 60psi and when it drops to around 40 i have to hit the button on the air compressor. Look up patriot sprayers you can just buythe pressure regulator and bag and hang on any sprayer that has a Schrader and relief valve like the longgray.I've got a bunch of co2 tanks from my paintball years, and I can fill it myself also.
