The curved side of the blade is called the "back" or "cambered side". The
flat side is called the "face" or "thrust side". The back usually doesn't
get many nicks in it. AC43-13-1B change 1 has all the information you
could desire about blending out nicks in your propeller, including
limitations. You shouldn't repaint the blade without closely inspecting
and repairing the nicks, You might paint over a developing crack.

Hi All

I'm repainting my McCauley Aluminium prop and was wondering if anyone
can give me some guidance in regards to the little aluminums dings
that occurred on the back side of the tip on the prop. These are tiny
dings the prop has picked up over the years from sucking up debris
while taxing. They vary from tiny pin pricks to small scratches,
maybe .015" at the deepest and maybe about .05" inches long.

I'm not sure if I should try and dress these out with a sander
(grinder) because to get them all out, I'd be taking off some serious
aluminium.

Any tips on sanding would be appreciated.

Thanks

Eugene
