[AT] Phosporic acid and cleaning a gas tank

[Kyle Sands]

Charlie - my first experience with muriatic acid gave me a respect for the stuff.  I was derusting some model T parts, forgot about them and came back a month later to find some destroyed (hydrogen embrittled) parts.  Thankfully, they weren't critical or rare parts.  

I used a 16oz. acid to 4 gallon water solution in this gas tank, so it was pretty week.  Still, given enough time, the acid can do some damage!
