Making a mess pre-shading

Just practice a lot. It'll come to you.

If the paint is too wet, try holding the brush a little further away. 

Do you have a double action brush? That's kind of key.

Hi. 
yea its double action - an iwata eclipse HP CS.

Hi everyone. 
Im not a novice to model making but pretty new to the use of an air brush. 
ive learnt to use very thinned paint to creat layers to help with pre-shading, but I'm making a mess using a dark paint, black usually, to pre shade with the paint running making thin lines all over the place. 

I'm using tamiya black with a white undercoat. I'm thinning it but having used all manner of ratios and unthinned black it's still happening. 

anyone have any tips to help here?

Cheers in advance

... paint running in thin lines all over the place ...

First guess;  air pressure is too high.     Back it off until it doesn't spray, then step up from there.

Second;  paint is too thin.   Cut back on your thinner to paint ratio.    The common comparison is 2% milk,  but go with what works for you

Yea, thanks. 
I did- there are so many. I couldn't find one that answered my question. 
cheers 

So really not that thinned? 
thanks

A good rule of thumb is practice anything new you are going to try, on a paint mule. It helps tremendously.

AMEN !

When you swish it around it should move like milk.

Welcome!

I usually build in 1/72 and 1/144, and pre-shading can be challenging with an airbrush. So I don't use one. After priming the model I take a soft charcol pencil and go over the panel lines. Then I use a paper stump/blender to fade the pencil line. A piece of tissue would work too. A light top coat and you have perfect pre-shading! This method makes it easy to pre-shade multi-color camo.

Genius. 
thank you
