Hi Everyone! I am working on a Shearwater 17 that has been in progress for going on 3 years. This is what happens when you have 2 children and purchase a house right after getting a kit. Well, we finally built a shop onto our house and the project is really back on track. I have a hull and deck together, all is looking well at this point and I am just sanding in preparation for glassing the outside.
On to my questions. First, I am concerned I am going to run out of the original epoxy which is now 3 years old. I have an extra half gallon of resin, and I am getting new slow hardener (MAS by the way). I am worried that if I run out of the original stuff after doing lets say just the hull, or even worse halfway through a hull or deck, what is the best way to assure an even color? Should I mix the containers of resin that is left, and use only the new hardener? What carries the amber color? Looks to me like it is the hardener just from observation as my resin is still clear, but the hardener is yellowish. Or... Just use the new stuff entierly? I kinda like the amber hue actually.
Second, how ridiculous do I have to be about sanding before the glassing. Specifically, when epoxy has stained the wood, but carries no wood flour or silica, will it just blend in when the whole boat is glassed? I am guessing you will never really get the wood back to its raw color anyway. So just remove any drips, scratches and decreeable bumps and make it all smooth?
Finally, it seems the instructions don't tell you to glass the cockpit combing ply spacers on the outside of the boat, only wrap it to the inside. Do you just make sure it is all coated in epoxy to protect the spacer from water? What about the edge of the rim itself on the outside? Cut it even? Same on the hatch openings, just glass up to the edge of the opening? Or do you have to fold the glass inside the hatch down to cover the spacers?
Sorry for the long post but I am just at that point of no return on a few steps and I just want to be sure! Can't wait to see this baby on the water!
