Oxidation need moisture and air. I've had partially used cans rust
from the inside out but never an unopened one. Most recent was a
third gallon of water base polyurethane varnish...it was so bad that a
hole developed in the bottom (from the inside) just from stirring.
The lid outside was fine, inside of the can - lid and sides - was all
rusty
I've had very little problems with the lids/rims. Some superficial
rust on opened cans, nothing major. Stored in my unheated shop in a
cabinet in Central Florida.
