It's the enamels that have dried up. Model Master is gone thanks to Rustoleum who owns Testors and there are few other enamel lines. Humbrol is still around but is weakly supported. Revell I think has a line but with very few colors. If you want acrylics, you can get those all day but I find them useless. They clog up my airbrushes, they don't stick and they have no wet out since they dry so fast.
