One simple improvement you can make is to clean the prop and give it
some polish. It really is the most critical aerofoil on your aircraft
and should be kept clean and smooth.

MIRROR FINISHED POLISHED PROPS

It is being rumored here in Kansas City, USA, that the local FAA
is taking a very dim view concerning polished props. Unless the
prop comes that way from the manufacturer.... it's considered a
modification requiring an STC - Supplemental Type Certificate.

I was referring to wooden props in my comments, though your point is
interesting re the 2025 props. if the anodised phlogiston spars (used
on RV's) have half the fatigue life of an alodined spar why is it that
props with an anodised finish dont seem to suffer a reduced fatigue
life?
beats me
