Is anyone using the 3M Accuspray guns with the replaceable nozzles? I'm a low volume user, a couple of gallons a month, but I need to be able to switch between higher viscosity (100 seconds #4 Ford Cup) pigmented lacquer or paint down to stuff as thin as 1# shellac. Except for shellac, I only spray WB products. I've read a bunch of literature and watched some videos of the Accuspray guns and it appears they can cover a wide range of materials, and are super easy to clean to avoid cross contamination. Not sure if I'd need to go with the air assisted gun or the gravity feed would work for my higher viscosity materials. The PPS cup system looks very nice as well, especially being able to spray upside down.
So I'm interested to hear your opinion on the Accuspray guns with replaceable nozzles. Like them, hate them, wouldn't use anything else, won't use them because of such and such.
I used accuspray guns for while before I went to AAA pumps. I thought they were great, the pps is the way to go. The little pps cups are great for doing samples.
I use one to spray polyester using a 2.0 tip and pressurised PPS cup.
I ended up buying a more conventional pressure assisted bottom feed HVLP gun, with multiple nozzles and needles, but I did buy the PPS cup for it. Sort of the middle ground. We'll see how the cup works. Thanks.
i use them only for fast cure paints like polyeseter, other than that i don't think they atomize that well put they do have a place in my shop for teh right application
I have been using the pps cups for several years and have never had one leak and I would't use anything else, hated cleaning the cups. I have and use all 3 sizes, never a leak.
Interesting. I use the pps system on a Sata gun (gravity), Iwata (gravity) and realize they are not pressurized. I also use them on my Capspray which is a pressurized cup and on my CAT gun which I pressurize from a regulator and I get no leaks. Maybe difference in new pps cups vs older ones
My pressurized controls are made by Cat. I will see if I can find a picture and post it here.
Having a drip in my solvent based finish means removing all that I have sprayed and starting over in the middle of a forward, completing process. Going backwards to go forward takes so much time!! Of course, I am thrilled.........
Go Cat's home page, there bottom left picture is captioned like "Go systems" or something. Any way their is a picture of a small vertical stack air compressor. Click on that and you will see that control unit attached to a syphon feed cup gun. Their control can be attached to a PPS system as well....
