Alodine and priming

[dwf2008]

Hi all,
I am just starting the tail kit for a Sling 2. Regarding corrosion protection, I am planning to use this process.
Wash parts with Bonderite C-IC aero.
Rinse with plain water.
Soak in Bonderite Alodine 1201.
Rinse in plain water.
Prime with SEM self etching gray primer.
Assemble and rivet parts.

Does this seem like a worthwhile process and not overkill?

Thanks for your thoughts

Mike Blyth himself has said that it's overkill to alodine and prime. Personally, I'm doing neither as I don't live in a coastal climate.

I will be using corrosion protection for dissimilar metals, like the stainless steel rivets, though.

I shot acid etch primer on everything, because I just wanted to play it safe on the interior parts, and apply a nice primer coat for the exterior. For the few parts that I've alodined, they don't need to be painted, as the alodine solution forms a protective coating on the parts.

I just got my jar of Duralac, so I'm testing using it between mating surfaces on the rudder. While it's primarily for dissimilar metals there was a recommendation to use corrosion protection on joints so I figured I'll give it a try. It's a bit messy, you get it on the clecos, but it seems to wipe off pretty easily.
