Gorilla Glue (and all polyurethane glues) has a short shelf life once
it has been opened. I don't think it can be thinned back to a useable
consistancy, but it wouldn't hurt to try (on scrap of course). It
will still work, but it is slower to set and may not have the
strengthn it has when fresh.

Is there a solvent/thinner that can be used.

From the smell looks like Alcohol could work.
