Touch up painting
Unless someone knows how to use a spray gun, and by that I mean has practiced enough to know the settings to do it right, I agree there will be lots of overspray and orange peel. My airport doesn’t even allow spray painting in hangars. Foam brush and foam rollers with the right paint, Stewart systems, for example, may work really well for small touch ups. It won’t look as nice as a good spray on however.
With that said, I do know of a painter in Torrance, he does the Shelby paint work and Sling aircraft. I’ll ask him next time I see him if he free lances. His work is excellent.
