Mark,

I've got OMS 98's also.  I haven't had this problem yet but I keep a close
eye on them for rust.  There are some chips that go down to the bare metal,
but I've found that clear nail polish works well to keep out the rust.  I
gusee the only thing you can do it treat it like a body job on the car.

First sand down the rusty area till clean metal comes up, clean with methyl
hydrate, not varsol, and prime it.  Allow to dry and prime again, then
paint.  Allow paint to air cure and don't heat the tank (i'm sure you know
this already!).  Don't forget to tape over or cover up the valves so you
don't get metal dust or paint in them.

HTH
Matt
