Reply To: Does matt Varnish go off? – Airbrush always getting blocked

I sympathise.  I have exactly the same happen every time I try to put matt varnish through the airbrush.  In the end I gave up and swapped to spray varnish.  Initially Testors and then when that was discontinued I use Mr Hobby Matt Topcoat.  Super flat finish without the constant airbrush cleaning.
