Alright guys, whittler, Big M, you others who airbrush, I've been having some problems with my Iwata bottle feed brush lately. The paint is seeming to have a tough time coming out of the brush when I only want a little bit coming out. If I pull the trigger all the way back it'll come out, but that is too much a lot of times. I've cleaned and cleaned but it doesnt seem to help much. My compressor, since I just got started about a month ago, is a Testors Mini Blue which puts out an invariable 35 psi. Is this a pressure problem? Something with the needle? Should I thin the paint? I really cant drop 150 bucks or more on a good compressor right now, so hopefully you guys have an idea. Thanks.

You didn't mention what sort of paint, but if you have to ask if you need to thin it, you probably do.

Your paint is too thick.  try mixing a few drops of water (use a medicine dropper) and mix well.  this should clear up that problem.  If you are using craft paint, you may have to strain it thru a piece of panty hose after you thin it.  Let me know excatly what brand of paint you are using.

just using createx colors

C-tex usually sprays pretty good, so now I'm thinking air pressure may also be causing some of the trouble.  Do you have this problem with every color you try or is certain colors?    Are you getting at least 20 psi on a consistant basis?  

yeah, i think it puts out at least 20 psi even when in operation. The "transparent" colors seem to spray a lot better than the opaque but the white is especially bad. I was having this problem before and found that tightening the nozzle helped, but that's not working now. I just have to figure something out, but it sure is frustrating. Thanks for your help.

Try backing the needle out just a little and see if that doesn't help.  also check the nozzle and make sure it isn't cracked.    Now c-tex is the thickest of the airbrush paints that I have used, that's why I went to wildlife colors by Smith Paint.  If you are in the market for some new paint I would highly recommend giving wildlife colors a try.
