[SEL] OT a little - galvanized parts....

[bill at antique-engines.com]

Let's say that we have a part that was originally galvanized. Over the
years the part was painted, rusted a bit, cleaned, repainted, painted
again, and now I have it cleaned up but the original galvanized finish
isn't what it should be on the top - the part people will see.
I want that original galvanized "look" back.
What can be done, if anything?

Fuel tanks are one example. Some brackets are another example.
