I know you are just dying to find out how the blister repair is coming along. So is my wife. Here is what the hull looks like after sealing, filling, fairing, sanding, refilling where I screwed up, refairing, resealing, re-re-sanding and re-re-sealing.
Along the way, I've had to invent several tools. My internal fiberglass patch derrick appeared in an earlier post. It turns out one big challenge is the interior of the centerboard truck, which was blistered just like the hull. Opening the blisters required putting a rasp bit on a drill extension to reach into the narrow space. To fill the divots, I cut the edge from a putty spreader and nailed it to a lathe. Sanding has been the tough one. While you want a barrier, you can't have it too thick or uneven, or the board will stick. Here is my sanding paddle, with sandpaper stapled to the end. It's not very efficient, but I am developing upper body strength.
And then how do you get all the sanding dust out of the trunk? Fortunately, I had just done a dishwasher install in our kitchen than produced a left over hose with a coupling that just happened to fit on the end of the Shop-Vac. To manipulate it, I taped it to the blade of a keyhole saw:
Not sure how long the rest will take. Never having done this before, every new container I open is a surprise. Interlux Wash 202 sounds like something you'd buy as a gift at Bed Bath & Beyond in the Soaps & Fragrances section. It turns out to be a chemical weapon that is banned in California. I thought it would be a good idea to try out Interlux Interprotect 2000 (an epoxy sealer, not a condom) on a small scale. One centerboard's worth of Interprotect 2000 is enough to totally dissolve interrelationship 2014. My data suggests that it takes two hours with all windows open and all fans going to reduce vapors to a recohabitation level.
Have you ever seen those film clips from the Shackleton expedition, where the crew are hitched up like dogs, trying to drag the Endurance through the ice to open water? That's what this is like.
