I'm going to be upgrading my current spraygun to a gravity feed cup gun. I haven't picked out the gun yet, but it will most likely require around 11-14 cfm at 40 psi or so. I'm looking to invest in a 5 HP compressor, either 60 or 80 gallon, and am just wondering whether I should go with a single or two stage compressor, and what exactly the difference is between the two. The new compressor will be dedicated for the spraying only, so I won't be running any other air tools off it.
Thanks!
