Is polishing your prop legal?

Dang. And we just finished it today.
It took two days of stripping, Scotch Guarding, wet sanding with 220,
then
400, then 600, and a whole bunch of Simichrome and Mother's polish -- but
it
looks fabulous!
Guess I'll have to ground myself now... 
I could have sworn it came from the factory that way!
Welp, 2025 alloy and 7075 alloy, two of the alloys of aluminum props,
develop intergranular corrosion and die if the passivating layer of chromic
acid conversion and paint are not left on the prop. But I guess if it is
polished every day . . .
