Help please? Airbrushing nightmare!

Gotta stir that stuff real good,sometimes more then just shaking.Some take the cap off and actually stir it with something.

Dear Elliboy,

I'm not sure, but I think the guy that invented acrylic paint is the same guy that invented the fish eye.  I've had the same problem with Stynylres, Model Master Acrylics and Vallejo Air, to name a few.  I find that a gentle, light swab with ordinary mineral spirts will usually end the problem.  Pull a cotton cloth tight over your finger tip, dip the cloth covered finger tip in the mineral spirits, just enough to get it damp, and use your finger tip to wipe down the model. When it's completely dry, go ahead and paint. I've also tried this using isopropyl alcohol, but it won't work.

Good luck.

With acrylics generally it's a cratering effect more so than actual fish eyes. Both look similar. I've generally found the cause to be the thinner I've used in a given paint or an additive and or as mentioned, how well the paint was mixed up. Some acrylics really do benefit from a power mixer like the little Badger battery powered unit.

Making sure the paint is stirred well seems to help . I personally drop 2 little stainless steel shaker balls in each bottle and use a Robart electric shaker . 

Low air pressure means wetter coats. If you're too close, pulling the trigger back too far with too low a pressure setting, you'll get fish eyes. You want to spray lightly, especially when spraying on dry paint or primer. The video below may help.
