Here is an illustration of what I guess are the anticorrosion effects of tannin. It is amazing. Ok I know a tank is not a steamcar but a boiler is a tank.
A Russian T34 tank was dumped in lake at the end of the war where it was covered in peat and mud for 56 years then discovered and hauled out in 2000. It looks almost perfect and the tracks even turned as it was pulled up the bank. There are pictures and Youtube video links. Worth seeing.
