Unpainted metal parts

[1990new]

Does anyone know if there is a particular reason why several parts under the dash were left unpainted.
Several of the brackets as well as the steering column are not painted and the leaking sunroof in Rosie
has caused all these part to accumulate surface rust. I plan to remove the rust and paint all of these brackets.
Any reason why I should not?

I'm sure it was just for cost and that no one sees it. Look under the dash of any other car out there ,same thing.

They are unpainted because they are not visible. They are considered to be a "D" surface. This is to save money. Automotive cost savings will demand an engineering change even for a few pennies.
O.K. to paint.
