Polishing your prop?

Is polishing your prop legal?

Probably not. See

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...

Ha! Yeah, I had it pressed and steam-cleaned, too... Sheesh.

My hands are so sore from sanding, Scotch Guarding would probably do them
good. How the hell do people strip planes for a living? And how do people
keep bare aluminum planes shiny?

Speaking of which, why is THAT legal, if a polished prop isn't? Weren't
those planes "painted at the factory", and now they don't have sufficient
"anti-corrosion protection"?

Actually, I believe most of the shiny, polished, bare aluminum planes I've
seen were not painted at the factory.

Paint is an option.

No wonder it took him so long. Maybe all that rubbing caused him to become
disoriented and all the Cardinals to look like upside down Cherokees

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 . . .

"Welp"? How'd THAT get past your chell-specker?

Anyway, of COURSE the very first flight we took with the polished prop was
to Door County -- where the plane literally spent 60 hours sitting outside
in the rain. (We don't even use water to WASH the plane, for gosh-sakes,
and then we immerse the bare aluminum in a shower for two days...)

Well, I'm happy to say that the Simichrome polish we used on the prop
apparently leaves some kind of a protective coating on the metal, because no
corrosion was evident when we returned. We gave it a light polishing when
we parked Atlas in the hangar, and the prop still looks GREAT.

(We actually had two line-guys on this trip comment on how good it looked!

Is Simichrome Polish the famous Prop Wash that I've heard so much about?
