Sotar 20/20 issue

a said it way earlier, and I will repeat myself - I see nothing that more time and practice with the brush will not cure. I've been using a Sotar since maybe the mid 90's, and have well, a few of them. Learn the paint reduction the brush likes, and it will reward you accordingly. Continue to try to push stuff it does not like, and you will remain frustrated by it... It is a trait that can be associated with the Sotar head that when you first depress the air, it will give a small paint splat - usually a very light ghosting of color. I have just learned to accept it, and work in a manner where it does not effect my outcome with the brush. Keep a small scrap of paper near your starting point, initiate you airflow over the scrap, and then move to where you want to work...
 
Not sure I follow. Pressure is around 18 psi. What you mean by this nozzle will be bad?
It will act just as bad... From buildup. The paint is too thick for the brush, struggles to get out and causes a trigger delay and a buttload of tip dry.
Thinning it more will actually lessen your spiders because it will be able to get out with less trigger pull, so less paint will come out.
When you find the good point you may have to drop pressure a little.
Seriously, try the food coloring on a test sheet and adjust pressure for it, you'll see the brush act as it should, then reduce the paint until it acts like the food coloring.
From what I hear, Vallejo flow improver also helps immensely.

Your results are roughly what you would get if you loaded straight un reduced wicked into that brush.

I found that they like a higher psi than my iwata's but as DaveG said they have their own little traits you have to work with. Try whats been suggested and you will find that the problems will either reduce or go completely.

Sounds good, will do.

Weird that this is the problem since it's Vallejo Air (supposedly AB ready) thinned additional 50/50. I'll keep working at it and practicing and figure out where it needs to be.
 
I’m sure I could put the Vallejo paint into my brush that has a .5 Nozzle and spray wide patterns without adding any reducer. If I wanted to paint a thin line using a .23 nozzle I would have to add a ton of reducer or I would end up with what you’re experiencing. 50/50 isn’t a huge amount. With Wicked Colours, I need to add about 5 drops of reducer to 1 drop of paint for small thin lines. Some days maybe more, yet Artists like Simon Murray use it straight out of the bottle.
 
Lots of paints say airbrush ready, but not always, I have used paint straight from the bottle but most of them you end up thinning in some way at some point. With Createx Wicked for example, a good starting ratio is 4 reducer/1 paint, depending on the airbrush and the weather/climate you may have to use more or less reducer/paint to get the correct flow for the airbrush your using. Even with 2 identical airbrushes you may have trouble with one but not with the other. So many variables but this is something you will learn as you go.

Createx restorer is something people really love for this

This is good for soaking the nozzle, correct?

When I google Createx Restorer 5619, I get 25 different looking bottles. Is it the 3rd from left in pic?

I can't find it any less than $21 w/ ship for 16 oz which seems pricey. Know of any places that carry it for less?

you have been using just water soluble, acrylic paints? Just pick up a bottle of 91% (or higher) Isopropyl Alcohol at the local drug store, or mega-mart... Should do the job. If in a pinch, a shot glass of Vodka will do just fine, too...

Small glass jar (like a siphon feed far) or solvent proof plastic small condiment tub is what I put my restorer in to soak in . I Haven’t replaced it in 3 years. It’s very economical

This is the one we talk about

I bought a 4oz bottle over 5 years ago and have not even used 1/4 of it yet. I put some in a small glass jar and am still soaking in that...

Awesome thank you. How long should I let it soak?

Also, I thought I remember seeing someone in this thread comment about a cleaning post that was stickied. Is this the one you guys were referring to? https://www.airbrushforum.org/threads/cleaning-and-sealing-and-airbrush.19833/
