RE: Why paint the bells of the trannies and not the laminations? Doesn't look right? nt

Reading around about how to deal with rust on a lamination stack yields some different opinions.
Some don't want to risk the lams shorting together (or something like that), which might happen if they are cleaned of the rust. Some have said that painting the lams could cause more heat buildup in the transformer.
Others say the lams can be carefully, painstakingly cleaned of rust and painted.
Either way, I would think it is mostly a cosmetic issue.
