52vff Don't try this at home ,I was wiring at a commercial oil field powder coat shop had the worst pitted wheel cylinder I had blasted and powder coated inside. Then Sunnen precision honed it back to size,it is still running on one of my storage rigs I use to keep brakes and driveline stuff alive. Now I don't know if domestic powder coat would work. There coating is used to protect oil field fittings from vicious downhole fluids in injection wells. .02 cents
