I checked Nelson's website, looks like they have plenty of Urac. I need to order some as I am down to about 1/4 pint.
I had a new pint but must have dropped it before I put it on the shelf in my extra full metal cabinet. Well, I had put a pin hole in the bottom apparent. Sure is hard to wash 1/2 of a pint of Urac off everything it dripped on 3 different shelves. Good thing it is water soluble, still took me the better part of a day to get things cleaned up.
