It this sink 100% porcelain or is it coated metal?
I believe it is 100%. The gouges are pretty deep (1/8") and no sign
of
metal. Also underside seems to be corrugated and not metal.

Could be enamel coated cast iron sinks like Kohler makes. In my
opinion they were and still are the best quality fixtures made. If
they were just painted steel you'd know it because gouges that deep
would reveal the steel. It's easy to tell by tapping on the sink bowl
with your knuckle. If it's a dull sound, it's cast. If it's steel it
will produce a tinny sound.

Sounds like cast iron, then...

The argument against replacing is that it is one of a pair of matched
sinks plus also matches the bathtub, toilet, and tiles. Plus, I
believe color is no longer actively in production.


Understandable. Perhaps you may want to contact one of the
professional outfits that recoat them and see if they''ll fill the
gouges.

Good idea, though would this still require removing the sink or do
they make house calls?
