Re: Gas tank resto kit

[Andrew Paroczy <evilone@dove.net.au>]

What bullshit are you on????? To get rid of rust, you need an acid .Rust
is also known as Ferrous oxide or ferric oxide , depending on the colour
of it,but for both, all you need is an acid to bring it into
solution.Hydrochloric acid or Phosphoric acid are my choice for this
job. Using a Phosphoric acid solution(mixed with water),just wash out
the tank,and,hey presto you get a protective chemical coating(iron
phosphate)and no more rust!!!!
