. Now just think what it does to your insides,
but at least you will be rust free. maybe all those French fries and squashed ketchup packets under the seat is a good thing. Keeps the floor pans from rusting.
I wonder how Citric Acid would work on it? Does wonders on the inside the Cooling system, then the CA is more concentrated than the Catsoup is I would imagine.
That is a good experiment on rust removal. It really did clean it up.
use some Phosphoric acid to etch the metal to give it a tooth for the POR to grip onto. That is what the metal ready is POR sells. after it dries, wash off the grey powdery stuff and paint it after it dries.
