In the early 80s, I bought a set of 3 T-Fal skillets, black porcelain exteriors over aluminum and non-stick inside. All three are still in use. The 10" I use regularly for potatoes. I peel and shred potatoes and pack them down in some hot oil in the skillet, turn when golden, reduce heat until done. I always use nylon or Melamine tools. The non-stick interior not only is still working, but it has no cuts or scratches and get washed in the dishwasher every time it is used. The exterior has faded to gray, but the pan is still flat after more than 30 years of use.
When I briefly worked at a kitchen store to pay for putting plumbing connections in my townhouse for the washers & dishwashers, they had a load of Calphalon that had a toasted oil varnish built up from lack of cleaning. I sprayed it down with oven cleaner and washed it in the dishwasher and it came out good as new.
