Hahaha! I don't imagine that the paint insulates. By savings i just meant buying a new fridge and the timer and cold mass. I can't recall if this one had an energy star rating. I bought it new in 2006 from a wholesaler for cheap because the door was dented.
When i started the cold mass and timer set up, I tested using a kilawatt. Running on the timer with cold mass saved me significant energy: a 15% reduction measured through AB testing. But i now have more cold mass than during the test, shorter overnight off priods, and a slightly colder thermostat setting, so 15% is certainly optimistic.
