Over the last year or so, I have turned more and more to Vallejo products. I really like everything that I have used of theirs, so far, except for the product mentioned in the title.

For the life of me, I can't get it to spray consistently from my single action Paasche airbrush. The airbrush work like a champ with everything else, but not the matte varnish.

I tried it a few nights ago for the first time with mixed results. It seemed to clog the airbrush really easily. I usually run my stuff through at 15 or 16 p.s.i. It sprays Model Air and thinned Model Color just fine, with the occasional cotton swab (bud) swipe to keep the tip clean. I tried the varnish straight out of the bottle and thinned with Vallejo thinning medium. I tried both with a .3 tip and a .5 tip. I tried both combinations at 15, 18, and 20 p.s.i., but still got intermittent spray, and an easily clogged tip. When I broke the airbrush down, there was a nice glob of the stuff on the portion of the needle where the fluid comes out.

Anybody have any experience with this stuff? The varnish that actually got on the model looks really good and I really would like to use it, but not with these kinds of problems.

Does the same with me so i have given up on it. Clogs the needle then splatters everywhere and ruins the model. I now use a Future/Tamiya flat mix at approx 3/1 ratio.

No problem with it.I use thinner 71.161 and flow improver 71.262

That is what I wanted to know. I am off to order some now.
After I posted my question, I did a bit more research and discovered that it was most likely the thinner I used. I used their thinner medium which, it appears, is for their brush paints, like the Model color line.
Thanks for the quick and informative response.

Hello Brett.
The Vallejo varnishes have several references in our catalogue, by the Model Air range, with the references Gloss varnish 70.510, Matt varnish 70.520 ans satin 70.522, ready to use with AB, using (like myself) a 0.2 tip Sparmax without thinn down it at all, is a ready to use varnish... You can find the reference Vallejo Premium Airbrush color Varnish, designed too for AB use, with the 62.062 reference. Hope this can help you...
