The inside seams went OK but it was not much fun. Lit with a torch, the process involved having your head stuck inside a kayak while trying to sort out laying a sticky glass fiber tape flat using a paintbrush taped to a long stick. Also the seams crept apart a little during the process which has meant using a bit of epoxy filler on the outside. Here is the first outside seam being installed, which was much more enjoyable. I have done the seams in four sessions, rather than trying to get the pairs done at once, and I'm glad I made this choice, otherwise it would have been way too messy!
