Well, this is a little late. Last week there was a discussion of fixing the rust spots on the galvanized pans of cages. I have salvaged several by using Rust Reform or Rust Converter and then using an acid resistant epoxy varnish over that. The reformer converts the rust and bonds it. Follow directions carefully and scrape off all possible rust. An old paring knife may be helpful in peeling off the rust. Sand it down and wipe off loose dust. After two coats are dry it can be top coated with paint but I prefer epoxy varnish, which in spite of the name is not two part, it is like a thick varnish without any drier. Last time I bought it I got it from Walter T. Kelly Co, (beekeeping supplies) Clarkson, KY. Maybe local paint stores carry it but I've never looked. Also if there is a local beekeeping supply store in your area check with them. The varnish comes in a quart can for $9 or $10. There will be lots leftover. Offer to do your friend's cages, and ytou can probably find other uses for it. It is sold for beekeepers to coat metal tanks. Walter T. Kelly Co.

Stand the pan on some scraps of wood on several layers of newspaper. Brush on the varnish and use less than you think it needs. Then invert the pan so the inside stands against a wall or brace it up so it is tilting somewhat. Check after a while and brush out sags. Excess varnish will slowly ooze toward the bottom and run out on the paper. Let it dry for a day and apply a second coat. When that is dry let the pan dry in the sun if possible for another day or so. Fingers, etc. can be cleaned with lacquer thinner. (No smoking! or open flames. Do this outside.) The varnish will resist urine, etc. It would really be best to use it on the pans BEFORE they are used to prevent problems. Also by using a cloth covering on the cage floor and a small kitten litter pan and 4" spring clamp to hold it in place a lot of rust can be avoided.
