I have had very good results using Vallejo Airbrush Flow Improver when spraying Tamiya acrylics. A couple of drops per cup of paint, so the bottle will last a long time.
Using the recommended thinner/poly additive with Mission Model paints, I have had little dry tip issues even with extended sessions. I REALLY like this paint.

GMorrison Airbrushing acrylics is definitely more difficult for me than enamels. Since I have a booth with a filter, I control fumes pretty well, and in every other way like enamels better. Back flushing a little helps too.

I prefer enamel, too. However, I can see the possibility of the demise of paints with volatile hydrocarbons. So I have set a goal of learning to airbrush acrylics just in case.

Modeling is an excuse to buy books.
My two cents is that what you're experiencing is pretty much normal. Acylics dry fast, especially when there's air blowing past them. Retarders seem to help, but I still get build up on the needle, it just takes longer. What works for me is to keep a Q-tip wet with lacquer thinner close at hand and just clean off the tip when it starts to get "dirty".
My airbrush has a tip guard that I don't use when I'm spraying, so a couple swipes from the gun to the tip clean up the dry material. That and a squirt onto scrap to blow off excess thinner, and I'm back in business.
Hope this will help you!
A drying retarder/flow improver can help as can thinning the paint more. Giving the needle a good oiling with arbrish lube can help too. Made a difference with vallejo acrylics and primers that were clogging my airbrush constanly. But in the end I still had issues and have stopped airbrushing anything vallejo. Tamiya and mission model paints have very rarely given me any problems and are now my go to.
hello SMH
when you airbrush do you do pretty much constant spraying or do spray a bit then look at is check that it ok than spray some more. if so it could be drying out in that time. i use vallejo paint in my Iwata HP-CP i don't have a problem with that. i also dont do long painting sessions. hopefully that is of some help if not hopefully someone more experienced can help you.
Like the subject says I'm having trobles with my airbrush tip drying out while painting with acrylics.
I use the paint stirght from the bottle and it sprays Ok at 20 psi but after a few minutes the tip dries out. I can get it broke loose by going full throttle, but it will dry out in short order.
