I've never heard of that. Very interesting. Maybe someone will have a comment...

Need help? Let me know!
I have heard about spraying a prop with "Pam" prior to any chance encounter with ice but waxing makes sense too. Water spray erodes seaplane props fairly quickly.

seawater (salt) spray is way more corrosive than rain (acid rain excepted). I am struggling to see the benefit from waxing. It is not like water is clinging to a spinning prop. What am I missing?
I've flown in lots of rain and snow over the years and never had any prop abrasion.
