I see you are getting as intense about it as I planned to! Unfortunately I realize that I don't have the time to do as much as I originally planned. My boat is on the hard at the Marina and they are starting to put them back in real quick. Plus, Spring was a real bear here in the North East. Luckily the weather seems to have finally broken and I think I am going to fill my keel Tomorrow. I am planning to use the marinetek. I have heard a few people give it the thumbs up. Nothing against West System Epoxy, just I don't think I need that much as their smallest can. I will probably sand it out and prime / or seal the repair patch. Then I am going to turn it over to the Marina and have them skip sand the bottom and put a coat of paint on it. Good luck and take a couple of before and after photos, I'd like to see how it turns out!
