Hey Guys,
I tried the electrical method without much success, but then I tried salt instead of baking soda. I've got another tank I could try it on. In any case the electrical method doesn't really get to the top of the tank very well. I guess it depends on where the rust is.
As for either method being more or less tree friendly. None of these methods generate any waste that isn't neutralized by just dumping the excess on an old slab of concrete. Except, of course, the electrical method which requires some coal fired generating plant to spin up another few kilowatts worth of acid rain.
Lastly, sealing a tank that doesn't leak is a real waste of tank sealer, your time and the value of your bike.
Check out my article in the articles section on rusty tanks.
