I finally finished building the magnetic mounts for the forward deck plate and found the gray I needed for the lower hull. So here's the boat with the hull in the proper colors and with the rust base color finished. Note: the photos make the colors look a fair bit lighter than they really are because of the very bright light on the ceiling above...
I also finished building the forward antenna rigging. That stuff is a real pain in the butt to do with those teeny tiny little insulator blocks...
Now I have a bunch of weathering paint work to do to blend the rust and add more variation to it. Then I need to paint the scum line on the hull and add some salty residue =).
(I fixed the dark streaks on the saddle tanks after taking the photos.)
