If the leading edges need protection with tape after a few hundred hours is there anything that can improve this in the manufacturing process?
Who manufacturers the tape that you guys talk about as a help in reducing the leading edge corrosion/erosion?
3M make blade tape

Bell used to specify one long length on 206 main blades.

Not recommended as firstly when its starts to come off you have a large piece of plastic whipping about, not good. Secondly hard to apply.
We had good results by using one foot lengths butted up to each other. Easy to apply and if it holes only a short length to replace.
We used to run the blades with tape till half life (1000hrs?) then just let them errode. Tape is not cheap
Your climatic conditions will affect the results, in Nigeria the tape on 206 blades did not last. One operator used to use metal epoxy filler and then reprofile.
Highly unlikely that this was Bell approved but worked well.
