Primed all the parts of the rudder. I used the same stuff as last time, Moeller's Zinc Chromate rattle cans. This time, I didn't worry about building an enclosure and all. I set a few sheets of plywood down in the driveway well away from the house. Then I roughed up all the surfaces really good and wiped it down with MEK. I gave a good while to dry and laid everything out on the plywood web-side down wherever possible. I sprayed the primer with a nice thin coat over everything then waited 5 minutes and went over it all again and repeated this until it looked nice and smooth. Then I waited 20 minutes longer and carefully turned over all the parts. Because the web-side was down, only the edges of the flanges came in contact with the plywood when I turned the pieces over. No scratches from the plywood this time!! I repeated the method described and let the pieces sit again for 20 minutes. One by one, I carefully brought each piece back into the garage and inspected each part. All but two stiffeners looked really good. I placed those stiffeners back on the plywood and made them right. There were a few places where I could have given it another shot, but let it go realizing that I was started to obsess. Also, another coat on the skins would make them look better, but I didn't feel another coat would protect any better. They're covered quite well, just with a little color distortion in some places. This will be entirely covered so that really doesn't matter as long as it's protected from corrosion.
