Yes if you are seeing a bit of rust, it has to be pretty bad where you can't
see it.
I'd have thought a stainless steel alloy with less ferrous content might be
the better way to go, take a magnet with you when shopping!

We have a very old white ceramic sink and draining board unit.
Rust is beginning to appear between the white enamel sink bottom and the
stainless steel sink drain hole.
Could anyone recommend a course of action and/or some kind of sealant.
Thanks

replace the drain
