Sounds like a bad idea to me, but have run into this before - does not actually seem to be against electrical code. It is real uncommon, but is done - but not mamny people like it, though some do tolerate it in tiny kitchens. More commonly, avoiding that, is drawer or cabinet inset microwaves. Reasons I don't like it:

1) rusting of the appliance from warm/hot moisutre rising from the sink, as you have experienced, which if inside the appliance, can cause dangerous arcing - all inside surfaces should be original plastic covers or special microwave paint which is metal-free so it does not arc. This special microwave paint (touchup bottles available at some appliance stores and at appliance parts vendors) should be used to touch up any chipped paint spots - but if actually "rusted" inside I would get a new one.

2) I don't like the idea of that moisture getting into the controls area - the touchpad control boards have VERY close wiring spacing on the circuit boards (commonly 12V rated boards wioth 120V circuits running on them), so free moisture/condensation could short it out

3) Unless you are pretty tall and have long arms, means mounting it low or forward where it will be an interference with your head

4) Risk of dropping dishes putting in and taking out, which could seriously damage the sink
