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.

When using the varnish use a cheap synthetic brush because you can't
clean it.  Don't use the disposable bristle brushes; they lose too many
bristles.  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.
 
I hope this helps
