I am working on a Artic Tern from Pygmy. I recently placed the fiberglass on the hull and have just put the second coat of epoxy on. My problem is, where I first butted the joints together for each of the panels, the wood color is lighter than the rest of the boat. I was under the impression the color would blend together with a couple coats of epoxy. Will this line of lighter wood always be there? is there anything I can do to fix this? Thanks.
