Thanks Elwell. It may have been that the store I bought it from (Michaels, the only art store in town ) did not handle it properly. It was so thick and pasty I'm surprised I stuck with it for as long as I did. Pouring it was a nightmare, I had to cut the plastic bottle to scoop it out. Plus... it smelled like a hair salon! Because of that, I hesitated to get another bottle. Now I'll just try a different store.
