I thought that would be a requisite before you even start working on the
tank :-)

With the electrolysis you don't have that issue. Though you will wear
out a prob or two. 8^)

Drywall screws seem like a good idea until they wedge themselves in
the corners of the tank. Then they are a right pain to remove.

For chemicals, I like the phosphoric acid because it changes the
remaining rust into a protective hard grayish-black layer.
