As I mentioned in several posts, I will be treating all the Fuel Tank parts (inside and outside) with Alumiprep and Alodine. I completed the bulk of this process in Part 10, but still have the Fuel Tank Skins, Rear Baffles, and long J-Stiffeners.
Since they are such big pieces, I obviously wasn’t able to “dip” them like all the other parts. So, I used spray bottles to apply the Alumiprep and Alodine. In the picture below, the six pieces have been treated and are hanging up to dry.
