Now I'm probably going to show the extent of my ignorance. Please be patient with me.
I went to wax my main rotors as suggested by Sharkeys and saw some pretty heavy nicks on the leading edge like a layer of aluminum was peeling. I have posted some photos here

Is this normal wear and tear and should these spots be repaired? Is there any approved tape for these like the big boys?
Also is there any greasing that pilots need to do regularly on these or any other maintenance that you guys do?
