I have a touch-up gun and an airbrush and a large compressor. I haven't used either of them for about four years. The spray cans work perfectly well for me and there is no clean up, just throw them away when they're empty. If you plan to use Lustrecote from Top Flite be sure you use the proper primer as it will eat its way through Rustoleum primer. Most Rustoleum colors are fuel proof to a degree and work well with Rustoleum primer. For other fuel proof model paints I have found Krylon primer works well.
