How you like the finishline gun compared to purple HF gun?
IMO, The D'ville paint's base better and the purple lay's clear better. The purple has a larger fan and seem's to atomize a heavy solids clear better.
The D'Ville also has the "bag" cup adapters to make clean up much easier.
You can get a universal adapter kit from D'Ville that will fit in most cup's,some need a little modification,that makes clean up quicker.
I've just alway's preferred a 2 gun system. One for paint,one just for clear.
Rarely do you shoot the 2 at the same pressure and gun settings and trust me,Once you find a setting on your gun that lay's clear smooth,you'll want to weld it in place.
You also eliminate the possibility of cross contamination of the 2. Nothing worse than having some color stuck in a gun that comes out in your clear.
Kandy's being the worst as the dye saturates into every possible crack and into the metal's microscopic scale. I have cleaned a gun THROUGHLY and leave some clean thinner/reducer in it for storage and the next shoot open the cup to see some of the residual kandy color in the thinner.
