Anyone familiar with Lab Metal?

I've got a small can of Lab Metal that is about a year old. I opened it today and it's extremely dried out. It's not hard, but pretty spongy. I'm wondering if anyone else here has used it and whether I can revive it with some solvent (for Lab Metal).

From my experience with the Hi Tem Lab Metal, if it's stir-able then adding their "lab thinner" a capful at a time until it loosens back up to a paste consistency should be fine. If the can has hard dried or flakey chunks to it then it's toast. So if its a chocolate moose or cheese cake consistency then you should be able to add thinner and be good to go.

I'm guessing it's on the line then. I'll try to add some solvent to it and let that soak in. Thanks.
