I’d second the badger 400 mini gun for larger surfaces. I used one for R/C model airplane painting, and it worked well for me.

one looks pretty much a badger clone, just liek my airbrush was, but it should do the trick, and the other is a 250ml spraygun which also looks like it would do the trick, which would be best? would be used to paint basecoats or mased off areas on pc case, xbox, and other things that size and smaller
also with these i shouldnt need to thin?
