A chemist told me rust does not spread. The top of my refrigerator gives me some doubt. It’s covered in these spots. The center of every spot is a small break in the paint, but the rust all around those spots is on top of the paint.

I think a sacrificial anode would only provide protection if the fridge were submerged underwater, or otherwise surrounded by an electrolyte.
Oh shit, you're right. Gotta keep the fridge in salt water, then.
