you didnt say how big your tank is but it should work just fine set the regulater at 45 get a water trap and mount it on your air line at at least 7 feet in the air when your spraying you may have to stop every minute or to to let the compressor catch up but iv used a small compressor for years with very good resalts you will need at least a 6 gallon tank you could plum a old propane tank in line on your air hose if your tank is smaller than 6 gallons good luck you can also get a low air cap for your gun i did that on one crafstman gun that i have
