I agree with Micro, a touch up gun is a good step up, when you get to the 4"
dia range, you can really lay down some paint.

OK,something about basecoating/primer.

I don't use an airbrush to prime or basecoat an entire rocket.
this is where spraycans work great.

primer is too high in solids and size of pigment to be airbrush friendly
automotive primer is superior to any airbrush primer, you won't find much airbrush sandable primer ( I haven't seen any)
plus I'm not worried about the finish of primer because I am going to sand it .
canned primer is the choice for me

I always basecoat my rockets with a spray of (krylon) gloss white (or black)
it shows every imperfection if I want to go anal on the finish
it provides a smooth clean white(or) black canvas to paint and nothing brings out colors like a white basecoat.
also if you like to wetsand ...paint is the best surface. wetsanding primer is often a waste of time unless you are capable of spraying a perfect coat of paint from a can with zero flaws or blushing on top of it. plus primer is absorbent...it 's risky to get it wet over a paper substrate.. if it's a fibergalss tube .. no problem.

I let spraycans do the "grunt work"
than hook up the airbrush.
