I have been looking at Zenair's Ch 701 STOL and nowhere have I seen any
mention
of treating the inside of the sheet alluminum for corrosion protection. I
would
have thought spraypainting with green (zincoxide?) paint woudld have been
necessary

The builders manual for the 601XL which I am building (and I assume the 701
and 801) suggests the use of Zinc Chromate or Zinc Oxide where ever metal
meets metal. Though with the 6061-T6 AL it is not really needed.
