Default Re: Tinsmith's in frame gas tank for cantilever Schwinn.

J.P., The metal we are using is call Tin Electroplate. It is sheet steel with a thin coating of tin electroplated to it. It's like nickel-plated or chrome-plated metal. The same type of process. Galvanized metal probably won't work too well, because using flux (an acid) in the soldering process will work on the galvanize and rust will likley occur later. The flux needs to be neutralized following any soldering in my book. I just wash the area with a baking soda rinse (alkaline). Sometimes soap and water will work, but not always. The guage of the sheet metal we are using on this project is about 28 guage. Hope that helps. Good luck, Dan
