Hi everyone, i ve been airbrushing for less than a year so still learning and experimenting. I ve been trying postshading and having a bit of trouble to do a nice job. I have trouble vecause they are too small spots
I airbrush with tamiya or vallejo air. I have an iwata eclipse.
I presume it s the pressure and surely the ratio of thinner/paint
Please help me !

Try... thinning your paints (more) and lower your pressure...
and if you have a fine needle and nozzle combo... that should work for ya .

Tamiya paints...??? normal thinning should be sprayed at 20-25+psi depending on where you live in the world and current weather there.... and airbrush needle size you are currently using... but for your highlights.... you will need to bring it down... 10-15 psi and have your paints thinned for that.... You will need to experiment ... as you and only you can tell if that is working for your application and A/B set up.

Don't try to do post shading with a large needle combo on very small areas... it won't work, Free hand that is ! Have you considered
using Cut masks.... and cover the areas you don't want highlighted ?

Practise doing very faint blotches... on paper towels, till you master the technique...
if you get spitting? you are trying to push paint that is too thick and your pressure is too low !

Play around till you get nice transparencies... to do that... paint some dark lines and spots on paper towels...
then go back with your highlight colour ... and try your technique over the dark areas you just painted... till you are satisfied with the results and
that is what you want to look like on your model !

if it needs 2 or 3 paint session to get ? so be it ! Less is more...
take your time and enjoy the process...

Happy modelling !

It's probably your environment. What type of climate do you live in? Humidity, ambient temp, barometric pressure all affect airbrushes. Don't be so hard on yourself until you have eliminated these other elements.

More joking around than anything. Spraying is an art form and done by sight and feel
There are so many factors in a good spray and you mentioned many.
Unfortunately with that many variables the opportunity for changes that affect results is rather large and can drive you bonkers
Don't even get me started on how one paint brand to another sprays, or even different batches of the same brand
Now golf on the other hand is an exact science with completely repeatable results

Have you guys been on other sites and had negative experiences or just got lucky like I did and found it right off the bat.

This was the first forum I joined. I checked out Armorama first, but I decided to join ISM because I liked the design better, of all things.

I joined FineScale Modeler last week, but I don't plan on using it much. ISM is better and I only joined FSM because I got a subscription to their magazine as a gift.

This might sound crazy but with tamiya you can almost draw pencil lines. Try around 2 parts thinner 1 part part Tamiya paint. Dial down the pressure to 5 PSI and spray Close, the result might surprise you
