I finally found a new (used but new to me
) tank as my other one was too rusted out to use. The one I have now has a "dusting" if you will of rust. You don't see shiny metal but it isn't flaking rust, if you rub it with bare fingers it will end up rubbing off where you can actually see the metal.
My question is do I need to "creem" the tank with that 3 part process to remove rust and coat the tank or can I do something else to clean it? The metal isn't orange or flaky just blackish as it had been sitting a few moths with gas in it according to the owner.
