Well, I finally got to the primer step last night. Lets just say, I learned a lot! :) My primer strategy (and there are MANY of them) is this. I am using two part epoxy AKZO primer on all ribs and spars, but not the inside of the ALCLAD skins. If the ALCLAD is not scratched it will provide all the protection I need from corrosion, IMHO.
So, essentially it is a four step process for me. First, I wash the parts with Dawn detergent to remove all dust, debris and grease. Second, I use Alumiprep 33 to acid etch the part and prepare them for Alodine. Third, I apply Alodine 1201. And lastly, I spray my primer. Well, the first three steps really went off without a hitch, a little time consuming, but pretty simple really. I used a small dunk bath for the Alodine and only left them soak for about a minute or two, a little on the short side but it seemed to work fine. Spraying the primer was a different story, mostly because I wasnt properly prepared...ie, didnt have a good system of hanging parts to dry. I only did a few parts before it got dark and I realized I needed to do a better job of preperation, I will finish this up this weekend and let you know how it went...and hopefully what I learned so that it goes a little smoother. Lots of lessons to be learned.
