re zinc are you suggesting that there is a big short position in 3 month futures that is not maintainable? Surely all cars are built with galvanized steel nowadays, even Russian Fiats.
Re BWR lagging today, it does that sometimes. Institutional investors lie back and then come flooding in. Wait for those multi million share days again and sell into it. Us little guys should buy on days like today when it is relatively quiet.

The better anti-corrosion materials and systems are, in order of efficacy - from Eshbach, 1934

1. Stellite (Niobium Steel)
2. High Chrome Stainless Steel
3. Titanium steel
3. Aluminum plated steel
4. Zinc electroplating
5. Galvanization

note 4 and 5 are not the same. 4 uses active current for even coating.

Aluminum plated steel will resist a salt water spray for 8 years. Zinc electroplating is markedly less good at about 5 years, and galvanization is lower still. Stellite will stand immersion in sulfuric acid for quite a while.

The benefits of coating with titanium nitride and iron oxide coatings etc.have not been tested but have future. Thick resorcinal polymer coatings with ferrous fillers or titanium/Ti oxide/glass strands may be effective as well and very tough. Probably work with brake drums that are not exposed to stone chips or could be shielded very easily. My single best material for corrosion resistance and toughness is fibreglass tape. It lasts forever, and anyone who has ever tried to get that stuff off a package will testify that it is well nigh indestructible.
