Report Bandai Gundam Gusion Rebake HG 1/144 in Space, Sci-Fi & Fantasy Posted September 30, 2019 Yes, mostly Vallejo air and color. Sometimes the gunze acrylics. I think I run around 15psi, maybe a tad higher. Normally I don't get spitting unless I'm trying to get the last ... little ... bit of paint. Self inflicted. :) I sprayed the parts for each assembly step separately so it was kind of a repetitive drill working with the airbrush. (Think exercises with a musical instrument.) And since most of the colors were mixes I could introduce a little variation as the build progressed.
