I've reached the point in the Rudder build that requires parts to be riveted together. So, in preparation of the riveting process, I began to Alumiprep and Alodine the parts this evening. I did the smaller parts in medium sized bins as described in previous posts and I will finish up the larger parts with the foam brush tomorrow. Once all the parts have had their Alumiprep and Alodine treatments, they will be epoxy primed with Akzo.
