Thank you Gomer P.
I remember using a protective tape on KH4 blades to prevent erosion/damage. Only problem the tapes used to come off after a while, whistling, ect etc. Most of the time we would take them off as it would put the track/balance out. BUT the blades leading edges did look better.
Any thought on it? and are the tapes still available?
Cheers
