Harbor freight spray gun?

Check the spray hole size to match these guns to to the material. IE. 1.4- paint and1-8 primer (read the paint can) Low pressure means a small pattern. The old bottom feed cheepie could spray a fence or semi trailer with 8" swath, these use 4" and spray water based enamel SMOG paint. go for it and see, the worst would be if you have to buy a $80 gun next.
