I use plastic chicken waterers in the summer and metal one with separate heated bases in the winter. My problem is that the water trough on the metal waterers rusts after a year or two and I end up replacing them at quite an expense. Does anyone have any suggestions how to keep them from rusting? Is there any food grade paint I can use to prevent rusting? I would love to keep the same metal waterers for more than a year or two.
