Re: Need advice on cleaning out my gas tank

I hope your tank lasts until you can get a replacement.

Historically, metal gas tanks were constructed of "terne plate", steel sheet coated with an alloy of lead, tin and antimony to make an inexpensive corrosion-resistant material. Various pressures over time, primarily environmental, health and cost, have changed the nature of the alloy coating to zinc and tin and more recently to primarily tin. Nevertheless once corrosion and/or mechanical forces have stripped this metal coating, you are down to naked steel and as Ross indicates, it will commence rusting VERY quickly.
