Gori or not, I have seen a bunch of people claim that they shouldn't coat their new bronze props for x months when new. There's no science behind this; we choose the variations of bronze for our propellers because of how close to inert bronze alloys are in a corrosive environment. When coated with propspeed or other silicone products it will have the best chance of staying in it's zen-like state without material loss. While yes, an uncoated prop will have migration of some alloy components to the outside, this isn't beneficial in yellow metal.
