hello, first time poster long time lurker.

I have recently gotten into the hobby again, coming from the army and deployment (kosovo) I have alot more time at home now as a Civilian.

I am currently working on a pz38t. I would like to give it a satin varnish to help the washes and decaling further ahead.

where I live I can pretty much only get Humbols satin varnish. My question is, should I thin it with humbrols enamel thinner or with water or not at all?

Is one coat with the airbrush enough?

regards
Charles

You can thin it with the humbrols enamel thinner or with whitw spirit.. Never with water or alcohol.
I would use a matt coat of varnish in your case.
