Galvanized waterer rusting - anything to repair?

[dman535]

Bought this from TSC and the bottom trough has rust on it. I clean it on occasion but it rusts up again. The manufacturer sent us a new one, but was wondering if there was anything to repair it?
When we bought it there was what looked like a paint on the lower are, that wore off and caused the rust. Can I do anything to it and not harm the chickens?

Mine have always rusted after a few years. I figured it was normal, and they need replacing every few years.

Mine too, and I do keep using them a while longer. Recently I bought the 'easy fill' waterers, plastic, and really like them. In winter, it will be back to the galvanized waterers on the heated bases. Mary
