As for the aluminum issue, here's the answer.
Aluminum degrades to Aluminum Oxide, which is sapphire, which is inert. The problem is(as in Rob's case) you have mechanical abrasion which eliminates the Al2O3 and exposes raw aluminum again. A common problem on boats. It can happen rapidly. If this is the case it will eat up like crazy. Aluminum is very corrosion resistant if, and only if, mechanical degradation can be controlled.
