I still use old can siphon guns for primary work.. My favorite primer gun is an old Binks 7 .. If your not use to squirting paint,, there is quite a learning curve.. But,, as with anything,, it'll just take a little practice [and maybe a lot of sand paper

].. I can't see a name on that gun where the name should be and for the price it has to be a cheap chinese piece,, but,, it still should shoot at least primer OK..
