Nice for clogging your
airbrush even if it's clinically spotless! Grrrrrrrr, mine's gone in the bin, and I'll not be replacing it either, QC is in question here.
its no use saying I must have had a bad one, this is the 21st century, Vallejo is the only manufacturer where I have had dodgy material from (Grey Primer, in case you ask!) for a long, long time. I love their
Model Air, but the varnish is too milky (spray some on a clear plastic bottle, and you'll see my point!) and full of tiny little half-cured lumps of goo (and has been from the start) and the Primer is not fit for purpose. Green primer is fine, so, you see where I am going here, I have to take a gamble, so I'm better off going with another manufacturer, where QC has been 100%.
So, back to Winsor & Newton Acrylic UV matt Varnish, works beautifully, and much cheaper to boot!
