Re: Tinsmith's in frame gas tank for cantilever Schwinn.
J.P., As far as a finish on the tank, if you are able to get tin electoplate and want to paint it you should probably scuff up the surface with a 3-M plastic pad to allow a primer coat of paint to adhere better, then spray on the finish color. If you desire the shiny finish I would wash it with soap and water to get any fingerprints off and spray with a clear finish. SB got some clear finish that is supposed to be resistant to gasoline, but I don't recall what it is. It's important after you get the surface clean of any fingerprints not to handle it with your bare hands. Probably should wear latex gloves. The natural oil from your fingertips will remain behind and over time will show up on the tin. Now it'll take a long time, but many of the tin patterns I've used over the years are are covered with my oxidized fingerprints. Hope this helps. Dan
