Paul:
Here's my educated guess: The engine produces a great deal of condensation
during its internal combustion and what doesn't come out the exhaust, ends up
in your oil pan. Even if the engine is not running, the air above the oil line
will also produce condensation. Water weighs more than oil so, especially if
left undisturbed, it will eventually rest on the bottom surface of the oil pan
where it can produce corrosion.
I do not recommend painting the inside of your oil pan. To minimize future
condensation and it's harmful effects, avoid short drives that don't allow the
engine to reach and sustain normal engine temperatures and change the oil often.
Take care.

Hi,
I've just had my oil pan dipped and cleaned with acid at the machine shop.
Although it looks shiny new, I wire brushed some areas. Why did it rust some
on the inside where 30 years worth of oil and sludge had built up?
Secondly, should I spray paint the inside of the oilpan?
Thanks,
Paul Dorsey- a long way to go
