I didn't restore Grandmas until it became apparent that I might outlive it if I left it alone; and that was an unacceptable thought.
It was developing black spots and pitting vs surface rust ... deeply blackened metal like that scares me more than orange surface rust. Black is deep oxidation about to become orange rust as most folks know it, that particular shade of blackness in metal needs to come off if possible. I've done more than enough metal work to know what will last in our climate. (I don't like a closed up house or air conditioning until it's miserable outside, drive with the window down summer or winter, etc.)
