ok six hours later the epoxy (hand lay up with MEK activator)ain't active. its like cake icing thats left out to dry... Im doing a rebuild on this kayak that got crushed by a tractor. (lol) yeah. so all is well till i go for the third layer of epoxy with the phene. glassballs mixed ikn to lighten things up and ease the sanding. Ive got some degree of hardening but not all the way around? Should I scrape it off or will it harden in a day or two. I guess imn a few drops shy on the MEK...ahhh well...it is a free kayak though..
