RE: Finishing for a TF GS P-51D
Thats a paint and set up problem. It may be too thick or you can up the pressure to 45psi. It looks like its shot at a low pressure and its too thick.
Up the pressure and test it. If not then use 40psi and thin it a little more then test it again. It should spray on thin and wet and when you over lap each pass they should blend nicely.
This one shot like it was wall texture! Lol
What paint system is it?
Can post photos of the containers?
