hi @walkwithme

well it deepend on what type of paint you use or just make sure your airbrush set are clean all the time before or after use. for vehicle airbrush im using auto paint mix with slow dry thinner , reducer is a must..and i use to mix 1colour : 2reducer. with 2psi airpressure from my compressor it flow nice and steady..but makesure do practice alot ..😉

thank you
