Hello everyone!
I recently bought an upgrade to my airbrush going from a Chinese knock-off to a Iwata Neo and one thing I have noticed when using it is sometimes I get a sprinkler effect of dots which I have kind of combated by thinning the paints even more. However my other problem with this is that they become to runny not so much they run free but they pool, I am not too sure if that is alright but when I watch other videos the paint goes on like a normal brush and dries relatively quick.
I hope you can help
Daniel

Do you have a water trap on the hose before the air brush? The compressor not only pulls air into it but also the moisture too.

I do have a water trap but I don't think its connected to it. The compressor I have is this one: http://www.ebay.com/itm/MULTI-PURPOSE-AIRBRUSH-KIT-Tank-Air-Compressor-Paint-Set-Hobby-Craft-Art-/190797728535

but I attach my hose to the side of it.

The moisture trap at the compressor is fine. What paint are you using? It could simply be, as you say, that you need to thin it more.

When you thin paint, it becomes runnier; to deal with that, you reduce the pressure (or spray from further away); also, don't pull the trigger all the way back. You should also get in the habit of cleaning off your airbrush tip and checking to make sure it's working properly by quickly spraying it on a piece of paper just before using on your model. a q-tip with some isopropyl alcohol to clean off any gunk that accumulates on the tip helps too.

The needle size versus what you're trying to pass through the airbrush matters too. For instance, if I'm using Citadel paint to basecoat, I'll use a 0.66mm needle, because I'm not 100% sure how consistently I've thinned my paint. Rather than fiddle with it, I just use a bigger needle. On the other hand, if I'm using Game Air or Model Air, I'll use a 0.35mm needle to do exactly the same task.

or maybe the PSI is too high?

Sometimes it's the consietency being a bit thin, it happens to me with Vallejo Air White. One thing you can do to counter it is to spray a quick burst away from your miniatures after each time you stop spraying to clear the nozzle. I've found that helps me out.

Thanks a lot, I am using citadel paints and am spraying at a psi of 15 so I may need to lower it like you say thanks again

I have had similar problems, however you can get a second water tap to attach directly to your airbrush which will eliminate a lot of the problems. It costs about a fiver from ebay.

If I were to buy a second tap what would I be looking for, all I can find is ones with a PSI gauge thanks.
