Barge can got glued shut -- suggestions?

Hey guys! I have a con coming up and I'm really crunching to get my armor done in time. I use Barge to glue the foam I use together. My problem is that my can has been glued completely shut, and I don't have any Barge thinner to release the cement gluing the cap shut. I literally cannot find anything on how to open it anywhere, so I figured I'd ask here. I'm so sorry if this is in the wrong place, I'm new here!

 

My suggestion is to buy a new container of contact cement. The dried glue is probably corrupting the wet glue.

 

I'm not sure what specific solvent is in Barge thinner, but you could try acetone or lacquer thinner to loosen the lid on your can. They seem to soften a lot of different paints and adhesives.

 

Honestly, when this happens to me, I end up using channel locks and some muscles. If you need, you can add a little more pipe to the end of the channel locks to give it more leverage, but I seem to get it to work without.
