I'm anxiously awaiting warmer weather so I can complete by Guillemot build. Hatches, finish sanding and varnish should take care of it. When I glassed the cockpit coaming lip, I got a few bubbles in the epoxy. I thought I could live with them, but it bothers me every time I walk past the kayak. I'm wondering if the following procedure would work:
1. drill a small hole in the hardened epoxy over the bubble using a drill bit between my fingers.
2. apply gentle heat to soften up the area.
3. apply fresh epoxy with a brush or syringe
4. massage the area to work the epoxy into the bubble.
