Hi
I have a lot of paints in various age, all at least 2 yrs old, up to 10. Now i've tried starting to paint again, but i'm having problems with consistency. Some are nearly airbrush liquid-y, some are thickfluid. I've tried using some airbrush medium or water on the thick paints to rather mixed effect, as it gets very liquid very fast, resulting in very poor coverage (wash/ink style on a non wash paint). Same with the paints that start too thin.
How can i get a more consistent coverage out of these? I'm assuming some of the older paints might be practically unsalvagable, but the ones from 2-4 years ago should be mostly fine, from experience?
I'm using a wet palette with mostly vallejo paints. Several i've already added ball bearings for agitation.
And no, im not using airbrush paints for a normal brush, those are in a different box.
Temperature wise i paint in a temp controlled room.
