So I have bought 4 cheap airbrushed to try my hand and see if I can do it. Harbor Freight siphon feed, Spray Gunner No Name, Master Airbrush, and a Neoeco SJ83 both from Bezo's 5 and dime. Used the No Name to primer and color some spoons to decide on which color to use. Worked OK on these small surfaces. Used the No Name for primer on the model and it did OK. Came with a 0.2 needle installed. I was not sure what size to use. Took forever, but was really smooth. Lost the nozzle while cleaning, small as the proverbial hens teeth, but have surmised.0.2 is probably useless for model painting anyway. Used the Master Airbrush for first try at color coat with the factory installed 0.3 needle. Really slow so I switched to the 0.5 needle and was better. When dry color was really splotchy. Not sure if I missed spots or it I was too far away and paint dried before it hit the surface. Quite possibly a little of both. I did two coats Tamiya X11 thinned 50/50 with Mr Color leveling thinner. 25psi airpressure. Decided to let it set overnight and try again the next day. Switched to the Neoeco, 0.5 needle, 18psi pressure, thoroughly stirred the paint as opposed to just shaking, lots of pigment in the bottom. Using pipettes 4 thinner to 3 paint. Used the pipette to mix in the spray cup. Success. Laid down really nice. Lots of coverage quickly. Neoeco puts out a lot of paint in a hurry. Really satisfied with the results. This is in no way meant to praise or disparage any of the airbrushed. At this point even though they are inexpensive units they are far above my ability. Just thought I would share my first airbrush experiences.
