It has been quite sometime since I updated on the boat project. The simple reason being that the project had not progressed much, thanks to the rainy winter weather in Seattle. I finally completed glassing of the entire boat. It is fine to just glass all the seams (strength), and the bottom (wear) of the boat. Since I had ordered tonnes of fiberglass cloth, I thought I will glass the entire boat including the insides. This gives the boat tremendous strength and durability while adding only a few ounces to the weight.
I had to remove the amine blush that had formed on some of the surfaces that I had fiberglassed. Then, I had to sand the cured surface so as to form a uniform as well as rough surface. If I were applying another coat of epoxy on an uncured surface, it would lead to a chemical bond (preferable). Since the first coat had completely cured, I had to sand it in order to form a rough surface for the second coat to cling onto. This forms a mechanical bond, which is not as strong as the chemical bond. Chemical bond occurs at molecular level. Enough theory now. The boat surface looks shiny and beautiful (see pic). Unfortunately, I have to paint it since epoxy degrades with exposure to sunlight. I will be completing the second coat on the outside and then painting the boat. Still thinking of a color scheme... The inside surfaces will be white or off-white. I don't want the surfaces to get hot in the sun.
BTW, we did watch The Sixth Sense last weekend. Of course, since this was the third time, it didn't grip us as much, but the ending did hit us well. I was observing the technical merit of the movie, and I have to say, it is a well made movie.
