Tom I know you are weathering also for other people - this car we see here, is this one of the cars you have to weather for MellowMike ?   
(sorry Mike, CNR)

Tom - What does sea salt do?

The sea salt acts as a mask. The blue paint is painted over the salt, and when the salt is brushed off, the rust underneath is revealed.

How long do you leave the salt on the rust primer before you paint another color and then (no and then) how long does the salt stay on before you brush off to reveal the rust primer.

Minutes:  I just wait until the water dries. 

I'm experimenting with when to take it off.  If you wait until the paint is dry, you get a very flat look.  If you wait until the paint dries just enough (looks waxy), you can brush it off and create blisters.

You are right, check out the N example...

Fantastic work Tom, you are raising the state-of-the-art to a new level.

And BTW do you use the traditional oils or water-based oils? (not the gouache, right?)

Thanks...I use the water-based oils.
