Varnish, round two

Well, I put a coat of varnish on the boat over a week ago.  It's would not dry.  Don't know what was the matter.  I called the paint co and the only thing they would do is check the batch #'s and see if anyone else had a complaint.  They also offered to send my money back.  I took that option. It took a can of mineral spirits an a lot of elbows to get the old varnish off.   Got different varnish.  I'll know tomorrow if it's me or the paint!
