For those who may read this I have drilled a 1/4" hole in the top of the lid and poured out small amounts at a time to use as it dries out very fast. I've been using duct tape to place over the hole, shake the can and let it sit. I've got a can I've "opened" at least 6 or 8 times and whats left inside is still OK. I just keep the lid clean and wipe it good and put on a new piece of tape.
Hope this helps someone... .and I don't take credit for this. It was suggested long time ago by another bolter and I tried it.
