I found that tomatoes will destroy Teflon surfaces.

Many years ago before the "cop killer bullets" thing you could buy Teflon spray in a can. Then some started using it on bullets and no more Teflon spray in the can.

And the many cases of Chinese armor piercing rounds sitting on the docks became out lawed as they could defeat body armor.

Many things happen because of "secret type" reasons.

The main reason they got rid of leaded fuels and leaded paint is because the lead interfered with the satellites and such.



The military still uses leaded paint "in certain cases". But you won't find much talk on it.
