Don’t ask how this happened. The solution: refill the bottle with straight acetone. It works; I have no idea what the “aromatic amines in the EZBond accelerant are doing. Any chemists in the crowd?
By the way Gorilla CA glue (not their polyurethane glue) is thicker than EZBond therefore runs less and eliminates the need for sanding out runs/drips. And being a CA, it also accelerates with acetone- I tested.
