I'm on my third Humbrol Enamel 49 matt varnish can that has turned into jelly inside after a few weeks/months and ends up clogging my airbrush. I thought it was just the pigments that I needed to stir extra thoroughly into the thinner inside the can, but I spent a good 10 minutes stirring, and while it looks good, it still messes everything up.
I thin and thin, and the varnish I pour into my airbrush cup looks good, but it still gives me these tiny blobs that gets stuck inside my airbrush and ruins everything. I don't want to experience this ever again. So what would be a good substitute?
Preferrably not acrylic, as it seems prone to cracking for no reason whatsoever. It needs to be able to go on top of enamel paints without making a fuss.
