Sandblasting, now there's a need for a big shop compressor.

If you have or get a dual action sander to use, they are pretty "air" hungry also. I think painting one of these tractors you could get by with a small pancake style compressor, like they sell that comes in kits with the finish air nailers. HVLP guns are great, easy to use, adjust, and clean, they are easy on air consumption and should not tax the smaller compressors what so ever.
I recommend a couple tips for you, one is get some type of water trap to use when painting, the ones that screw on to the air line at the gun that are disposable work great. Also, you mentioned bugs getting in the paint, if they do, leave them till its dry, trying to get them out when the paint is wet will make even a bigger mess than the bug did to start with.
