Textured surface

Way too much pressure, drop it down to about 15. Sounds as if you're applying too much too fast at too high of a pressure which is essentially plastering on the paint like that a contractor would do on walls in ones home.

Probably requires that much pressure if the paint is onlly thinned 3:1. Thin the paint more and reduce pressure to 22PSI or lower. The Paasche H may have trouble drawing paint at 15PSI. Start around 22PSI and try lowering the pressure from there. As Gerald said, at the moment it's the modelling equivalent of blowing cement render on a wall.

Sorry for the late response, work schedule! Thanks for the help. The 3:1 thinning is per their recommendations. I will try thinning some more and reducing the pressure. Hopefully I will get better results.

3:2 paint to thinner and 22 lbs works great with my H.

3:2, that is opposite of thinning it more. Is this using the H-3 nozzle? I will give this a try as well, especially since I know you are using an H brush. But it definately looks like I am using too much air pressure, so I will dial it down too around 22 psi and play with mixtures. Thanks for the advice

What am I talking about, that is thinning it more. Sorry about that bouttime, had an "old fart" moment. I will give that a try, thanks.

Forget mix ratios.  They will change from brand to brand, bottle to bottle.   You mention flat black.  Because I am constantly opening my flat black to do a touch up or darken another color it gets thicker over time.  So you will have a different ratio even in the same bottle. SO again... for get mixing ratios.

You will hear folks say to get it to the consistency of milk.   I always mix my paint in 1 oz plastic dose cups.  I put milk in one and tipped it to see what it looked like running down the side.  I mix my paints to look like that and have been a happy camper ever since.

That is an excellent idea using a cup of milk for a visual. I wonder if whiskey has the same consistency of milk. Better not do that, I'll end up painting everything else but the model!
