Epifanes Question

Posted by Parke on Oct 16, 2006

I'm using Epifanes varnish on my deck. I had two coats on the deck and than painted the hull. When I went to finish the deck, I opened the varnish and it was very thick and lumpy, almost gelled. It would not filter. I store it at about 66 f. Can I just thin it or is it ruined? What is best to thin it with?
