Preval paint system??

since i moved 550 mi south to Texas here, i am without a compressor for the time being. mainly wondering about this system to shoot some DTM primer, and maybe some acrylic urethane n an engine bay. if i do the bay like the factory, with runs and crappy job it would look just like they came from the factory decades ago! ha
if this thing i used more than once, a good clean up with laquer thinner would be mandatory for sure, but not sure what it does to that plactic head!!
