Took a look at the prop after haulout. I think it is the original Ericson prop: 15 RH 10 Nibral 2-blade.
I'm not sure what a Nibral prop is supposed to look like. Mine has a gray-ish layer (oxidation??) over the metal. There are a few areas with redish rust-like spots (I know there is no iron in it).
I started wire-brushing it down to see if I could get it back to bare metal (but then wondered if this is a good idea). Does nibral form a protective anti-corrosive surface like aluminum?
Should I leave it alone? Finish polishing it up? Get it down to base-metal and then paint with Petit 1792?
Thanks.
