guns a piece of crap, i got the 200 mix gun. ok prinicple but totally reliant on cheap orings (poor machineing). Gun ONLY SPRAYSON A DOWN ANGLE, AND GELCOAT POURS OUT IF YOU DONT FLIP IT UP WHEN DONE SHOOTING. The only real purpose for this gun is shooting molds. dont expect to do finish work. i would not buy it again, i wind up only using mine for shooting customer bilges where i need to dump alot of material.
You can use mine. It Works fine. I would think a cup gun isn't used for spraying molds unless they are really small molds for some gadget or something. It is far better than rolling or brushing at finish coats. It wasn't gel coat but I've sprayed thousands of gallons of 2 part duraine and bostic . They are urethane primer and finish. however they are spelled:grin: Maybe I am just doing something I don't know I'm doing due to past spraying history??? Or maybe the others are using the wrong gun for the purpose it was intended to be used for? Again, mine works fine and it is what I used to spray the duffy hull finish coats.
