You can paint with one like that with only a couple of problems. It's going to cycle fairly quickly, and quite often. The second issue is...it's a single stage. Recovery time is going to be a little slower, and with that, heat will be one of your big concerns. And you know as well as others do, a single stage compressor generates quite a bit of heat and along with that come moisture. So you'll need to make sure you have a good water trap close to the compressor and also close to the gun. You can get one of the water trap balls that go at the fitting of the gun to trap moisture before it gets into the gun.
Whatever you are painting, when you have a little free time, do a dry run on the vehicle. Just take your gun, hook it up, set the settings at the compressor and adjust the settings at the gun and air paint it. You could also have a buddy in the background playing the air guitar just so you have something to listen to.
All kidding aside, air paint it with the correct settings to see the cycle times. How often does it take to start, how long does it run, and are you maintaining good pressure at the gun throughout the cycle times?
Then you can adjust yourself to compensate for what is lacking, where. Instead of shooting the complete topside, you may have to shoot the roof, cycle, shoot the hood and maybe even the trunk before it cycles again. Then either make a mental note for the big day, or even write it down on a whiteboard and hang it up so you remember.
I have a buddy that has completely rebuilt and painted (show quality) a '69 Camaro, a '67 El-Cee, and a '80 Malibu all with a small cheap horizontal pull around compressor. IIRC, it's a cheap Sears model, maybe 20 gallons. He would make a couple of dry runs before he painted and adjusted accordingly.
