airbrush problems

I had that problem at first with my Aztek, try tightening down the tip some more, that did it for me, for a while anyway. I have gotten to where I don't like it at all anymore. I even take the tips apart and clean them very carefully and thoroughly, but it just doesn't seem to work consistantly, the flow changes and it only works intermittently when I'm spraying.

Just today I ordered an Iwata revolution gravity feed double action. It looks like a good brush from online comparisons, nobody in my city carries anything but pache and aztek, so I couldn't play around with one to see how it felt, but I've read good stuff about them. The price was right from DixieArt, and I took the plunge.

The power of deduction my Dear Watson!

If you have used two guns... and neither spray paint.

The problem lies in the paint or in how it is being delivered to your gun.

Make sure your paint is thinned and doesn't have gobs of goo in it, try different paints.

Make sure you try to use something different to deliver it to each gun for testing. I am thinking that your cup is plugged up and after you filled it with paint to find it didn't work in one gun. You transferred it to another gun and found that it didn't work either.

Try a different cup. :)

well, i have tried different cups and different tubes in the cups, and the paint is Testors Model Master semi gloss white...i have it to the consistency of milk, and it doesnt seem to have any clots in it.

Ok.

Spray thinner through the gun... no paint. Try both guns and different cups.

I have an Aztec 470 and had the same problem. I was tightening the nozzles too tightly. I'd get plenty of air flow, but no paint. Back the nozzles off until they're just barely snug to the gun. They'll work fine.
