[TheForge] Aluminum corrosion

[David E. Smucker]

Zinc Chromate still is the usual primer -- follow by a good quality paint.

I would check out the Naval Jelly product.

The industrial procedure is to caustic clean dip, follow by a nitric acid 
dip, follow by a warm water rinse.
Then prime, then paint.
