Sorry; I think I just sent an empty posting!
Frequently when repairing medium format and 35 mm cameras one must lift the
leather to get at screws. Typically there is corrosion under the leather
and I assume it is either chemicals in an animal skin or chemicals used to
process the skin to leather which cause the corrosion. The question, is
there anything to do to prevent such corrosion in the future? The obvious
possibilities are treatments of the leather (maybe to neutralize acids,
such as tannic acid or others (chromic acid?)) or an impermeable barrier
which blocks the troublemakers from reaching the metal. Of course, the
leather must not be harmed in either the short term or the long term.
Can one wash out whatever the source of trouble might be and then soften
and protect the leather with some kind of oil which does not prevent
adequate gluing to the camera?
