I built a CLC 17 ft kayak about ten years ago when I was a teenager. It was safely stored in the attic of my parents' garage for a number of years, but I recently moved to the west coast and took the boat with me. I've refinished it twice over the years, the last time being just less than a year ago. Unfortunately, I no longer have anywhere indoor to store it, so it is currently hanging off of the back of my fence.
I just noticed the other day (after a lot of rain) that the wood has darkened a bit on the top of the kayak near the edges, as though some water has been soaking in from the joint. Obviously I need to keep this thing covered with a tarp, but in terms of the damage that has already been done, I'm wondering what I might be able to do to repair it?
