My coffee pot was abandoned outside for a few years where my daughter put flowers in it and left it in her play area. I thought it was a rock. The rust was all over. it. My heavens, what a remarkable change. It is now in the house we serve coffee for guests. See for yourself. I have the picture! They do a lot of plating or coating for cars rims and motorcycles. Who would have thought they did such delicate work. BRAVO to you Gill.
