For aluminum protection: Watch the EAA Hints for Homebuilders video and do what Brian Carpenter says. It works! http://www.eaavideo.org/channel.aspx?ch=ch_hints
Anodize is the best (and pricey) aluminum treatment, but next best is alodine and doable by anyone right on your work bench at home. Zinc chromate is a good primer for a finish coat of a spray paint, but next to worthless for aluminum metal protection. Powder coat is a great looking finish and will provide excellent protection as long as the surface does not crack or get scratched to the bare metal. Corrosion can then happily eat away under the best looking part and you will not know it until the paint can no longer support the load that the metal used to carry.

From Sonex builders' sites I seem to remember there's a zinc chromate (?) spray that people use. What do you think is best? Thanks for any suggestions... Seth
