Paint gun recommendation

First determine how many coins you can spend initailly.
Spend most of that on air volume and quality.
An aftercooler may be needed but a coil of air hose in a bucket of water serves the purpose. Then a good air filter. Then buy a cheap gun and practice, not only the shooting but the disassembly and cleaning. Paint lawn mowers bicycles, whatever. Like , "How do I get to Carnagy Hall ?" "Practice, practice" You can shoot primer on your car with it too.
Primer and underside of hoods and trunk lids is about all this gun will be used for eventually. Hopefully you have been saving up during this period.
The time to buy a quality gun will come. Treat this gun like a surgical tool. Keep it clean, properly stored ( hidden ) and out of the hands of kids and neighbors. I've seen some nice guns get bumped of the workbench and hit a concrete floor, or epoxy primer left to dry inside, ruined one way other another.
