Hi all! I am a newbie and have had some problems with my first two attempts working with an E-Tank. I have a Shumacher charger with a handle and wheels. I set it at 40 amps/12v. The pans are suspended in a waste basket with water and Arm & Hammer Washing Soda. I am using a sheet of steel for the sacrifice metal, which I believe is stainless steel. I used the same water for both, but added more of the washing solution for the second pan. After they were done, I scrubbed them with an SOS pad. When I was ready to season them, I noticed that both pans have a fine crack that starts on the inside of the pan, but doesn’t go all the way through to the outside. Because the cracks are so similar, I feel that I am doing something wrong. Please help me as I am so interested in making this happen. Thanks!
