Thanks for the responses!
I have not cleaned the baits before painting, so I will try that.
But I also am most likely adding layers too thick and too quickly.
I usually apply a white base coat ( all one layer) then use a blow dryer to heat set for 30 seconds or so.
Then I move on to the colors and heat set between colors.
I then heat set, add eyes and dip in the MCU
Im new to airbrushing and maybe I need to learn to do multiple layers with the same color before moving on to the next color.
Does a blow dryer heat set the paint enough, and does 30 seconds seem long enough to heat set?
