Making a mess pre-shading

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

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.

Welcome aboard,before jumping in you should investigate all the different sections of the forums,will be very helpful to you

… 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

Welcome. Try asking in the paint section. You’ll get better responses

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
