Thanks guy's. And yes the spray gun I am going to buy soon is a HVLP and also going to be running 2 and maybe 3 DA sanders at once sometimes because a few friends are going to come over to help me sand this whole car down to bare metal by DA sanders. So I am going to have 3 going at once and maybe if I get someone else too then get my 15gal compressor on another DA. But yeah the compressor I have now is a 5 HP 15 gallon and it's not big enough and runs constently with just one air tool.
