Paint utilizing aluminum powder would not easilu "corrode" and form such a
film because it is wrapped in a carrier/vehicle material that protects it --
it can (CAN) retain its glimmer.

Now, you could also argue, that aluminum flakes or pigment in a paint has
different reflective properties as an aluminum sheet. And flakes do "glimmer"
less than a cast or machined or polished aluminum block.
FineScale Modeller had a avery nice article about 4 years ago about creating
different levels of "shine" and weathering on model aircraft. The gentleman
used the metallizer paint, which unfortunately may not be available anymore. He
managed to use different levels of buffing and treatment to simulate the
varying degrees of discoloration and aging on an airplane. On the main surfaces,
the hot zones near the exhaust, crud in the underframe, etc.
So rather than to discuss the "right formula" it would be IMHO better to
determine what is the best technique to represent the effect of a new vs. old car,
as discussed to some degree here.
Anyone tried to paint a "silver" tank car with metallizer paint? And match
The topic of truck/body color has obviously more applications in the
Passenger car arena... I have plated passenger cars and "silver" plastic cars. Neither
one looks right. So there is work to do. Another topic for another list...
