The base of my microwave where the wheels run around has corroded and
the
paint has flaked off in the track. I was going to paint it with
radiator
paint - okay so I happen to have some radiator paint.

Any danger?


Youd need to make sure the rust is removed and hasnt gone through, or
gone deep enough that what metal remains is no longer good and strong.

With commercial kit, any such rusting constitutes a safety failure,
even when it does not cause leakage, because it is hard to know when
leakage might occur.

I wouldnt do it unless you know what youre doing, and are able to
competently determine that its safe.

Any paint would need to survive boiling point, and be based on a
rapidly evaporating solvent so that no solvent remains when the oven is
first used. And of course the oven would need to be well ventilated for
a few days to ensure no solvent remaining.

I'm not recommending doing any of this, as if you goof up there could
be some risk.
