I was reading the paint storage thread and got some good ideas about how to store paint (and a great tip about donating extra to Habitat for Humanity,) but what about when you find paint that is too far gone? I'm talking 20 years old where the chunky liquid is concealed by a 1/2" thick solid skin on top.
Where I live, the only way I know is to dry it all out on a drop cloth or mix it with kitty litter to solidify everything, then put it out with the rest of the trash. As far as I know there is no nearby recycling for this.
Anything I'm missing? Thanks.
