Re: Cans rusting... Some of the remedies I've seen are to dip the cans in melted parafin. Or spray the cans with polyurethane (food safe when fully cured, according to several sources.)
Remove the label. Treat. Reattach the label. Or remove the label, use a permanent marking pen to label before treating the can.
