Welcome to Librarium Online!
Looking for a new vanish product that I can get in the UK.
I usually use GW purity seal and its been fine for over a year but recently whenever I try it out on a test model it goes misty looking, I first thought this was because of the recent cold temperature outside/garage but its not any better inside. (I have had the can over a year, maybe its just past it).
The army painter matt varish is good but shake it well before use.
Brush on Varnish eliminates the cloudy problem. GW, Valejio and PP all make mat varnish in pots.
Quorn! - Protein for the Protein God.
Rustoluem brands work well for me. 1 coat of gloss and 2 coats of matte to dull it down. that and they are Cheap.
