I don't see why it wouldn't work. I see trim carpenters spraying stain & lacquer all the time with smaller/portable comps like that. It will just run more often then a larger tank compressor. I haven't painted with a compressor for a long time so somebody else can chime it on this - but I THINK you only need about 40 psi to run a spray gun.

BUT you may want to consider a bigger unit that goes upwards of 140-150 psi. You will want to start using it for other odd jobs around the house and you might find the 100psi to be limiting - such as removing over torqued or rusty lug nuts, removing the lawn mower blade, other similar large nuts via an impact wrench, shooting nailes through your skull (just kidding [8D])
