I do not remember the formula
Does this help? I did the rust treatment from the inside. All the rust was the size of sand. Nothing larger than a grain of sand. No chunks, no flakes. Just surface rust that was washed away.
BTW, I never once said that I was not going to have the tank tested, or even use it as a compressor tank, you guys assumed I was not.
