Inexpensive paint, gun worth considering?

The Harbor Freight Black Widow shoots OK, it does leave a little orange peel to cut and buff. It is OK with metallic paint, seems to get boogers on the needle tip if I didn't clean it every other cup.

I have other off brand guns I can't get replacement parts for after just a few years.

Devilbiss has parts to adapt, rebuild and replace for decades. And I still use my Devilbiss guns that are about 35 years old and have no problem getting parts to fix them.
