Wing rib priming - View Thread
After deburring the ribs I scrubbed them with Alumiprep. Once all the parts dried, I started the Alodine process. I built an Alodine bath for the ribs out of wood from the wing crates and some plastic drop cloth. After aloding the ribs, I painted them with primer.

Wing rib priming - RE: - View Thread
After the normal regiment of deburring all the edges and holes, I scrub the ribs with a red Scotchbrite bad and AlumiPrep 33 solution prior to Alodining. This seems to work well for making sure the surface is totally clean, while at the same time 'etching' the surface and giving the primer something to bite into. Ah! A primer question. When I started my build I got a lot of credible input from both sides of the priming war. I basically decided I would prime to 'play it safe'. I figured any added weight and effort from the priming process would be worth it to me if it provide any ounce of corrosion prevention or increase in re-sale value. That left me with the decision on what type of primer to use. I chose the Azko two part epoxy because it was the only primer I could find that provided a moisture barrier without an additional top-coat. Seems to me that keeping moisture is key to preventing corrosion. If I went with the rattle can primers, or any other type, I would need to add a top-coat to get a moisture barrier. Additionally, my experience has shown that the 2 part epoxy primer is a bit more durable then the rattle-can primer and it really does not take much more effort apply (just some added clean-up time). That said, I do keep a few cans of Napa 7220 on hand for small little touch-up jobs (i.e. dings from the bucking bar, etc).

I found an excellent tutorial on priming on Dan Checkoway's website. Go to http://www.rvproject.com/primer.html.
