The "stop/rust" thing (I've used Extend, seems OK, some people
really like POR-15) will stain paint and make it ugly, so watch
where you splatter it (also try not to run over a whole plastic
jar of it with your bus (don't ask how I know  :-)  )).  I don't
think it will make the paint chip or crack, BUT, if there is
rust under the paint, it won't prevent it from spreading.  A typical
bubble of rust has spread underneath normal-looking paint so
when you're sanding, make sure you get to bare metal or at least
get off all the paint you're sure is above rust.

Also there are lots of hidden areas that you can't really reach
into to sand or paint--chain saw oil or motorcycle chain lube
has been highly recommended to slow rust in these areas.
