Now I just used a 2.0 tip on my epoxy primer inside the cab, but it was because of the guns design that I used it. And it PILED on that primer!

I WILL NOT be using that big of a tip on the outside or dash or anything that needs the primer applied properly.
Now understand, you can get away with it, if it's warm out, if you have fast gun movement, little overlap, a bunch of factors can keep down the film thickness and solvent being applied so you don't trap it. So you can get away with it, I just grab a different gun to solve the problem.
Solvent entrapment is the number one,
NUMBER 1 cause of paint failures hands down. So you want to do anything you can to avoid it.
