Hello and thanks for all the great anwsers to my questions.

Now another one :

How could I simulate sand dust on a glass ?

Would thinned buff airbrushed work well for this ?

I came across this article doing research on building Hummers...

Hope this helps.

That should work just fine, just remember to mask the area the wiper would clear. You can also simulate a wiped clean area by putting a little gel toothpaste on a microbrush and gently rubbing over the buff to reveal the glass below.

Thanks for the link and the tip !

You should try pigments.

cheers
