My best specimen from Tucson 2003 is (drumroll please)... a rusty 19-pound

(Hey, we can't ALL offer $5k for the nice bullet-shaped pieces like some
folks can.)

I want to clean this sucker up, but I need advice. I believe that there
should be four steps in the process:
(1) Brushing off the rust
(2) Soaking in a chemical solution
(3) Baking in the oven at 150 Fahrenheit for a few hours
(4) Coating it to keep moisture out

Step #3 I think I understand well enough. :)

- Is there a certain type of brush to use? Wire, of course. Does it matter
what type of wire? Can I put something on my cordless drill to make it go
- What is the chemical bath formula? I know I've seen it here...
- What should I coat it with? I'm thinking of using the type of oil used on
gun barrels. Yes/No? Other options?

And, as ever, is there a really good, accurate, step-by-step web site that
covers stabilizing a rusty meteorite?
