Default Catto LET (leading edge tape)

I am considering applying the Catto LET, leading edge tape, to my three blade Catto prop. It is claimed to help or prevent erosion to the leading edge of the propeller blades.
Does anybody have any experience using this product? And if so what are your thoughts? Does it work as claimed, are you glad you did it, would you do it again on another Catto prop?
Thanks in advance for any and all comments.

Have flown 500 hours, through occasional rain and occasionally off grass and gravel strips. The tape is a bit scuffed and nicked in places but the underlying prop is in perfect condition.

Thank you. That is exactly what I was hoping to hear. Was it hard to put the tape on?

I use LE tape & have also found it protects my vintage 2005 prop's leading edge from nicks & rain damage.

I have Craig's three blade with nickel leading edge but he also puts the tape on the inboard section of the blades where the NLE is only on the last 12" of tip.
My tape has held up well with 450 hours and lots of rain. If I didn't have the NLE I would sure use the tape on the entire edge.

I use LE tape on the entire leading edge of my 3 blade Catto and change it every other annual or unless it needs it earlier. Harder to get off the longer you leave it on in the Texas heat.

Tape works well at preventing rain erosion however...
It is hard to get the tape to adhere to the curved tip of the blade without buckling and failing in that location.
Due to the above, the tip is unprotected and erodes on the leading edge.
After one good flight through rain, my experience is the tape gets damaged to the point that it requires replacement.

I have an older 3 blade Catto on my garage wall due to too much leading edge damage flying through rain, mist, etc. If it were one of his newer ones with the nickel leading edge, I would likely still be flying it today.

I used a prop tape from Spruce and followed Catto's installation guidelines. Not sure which one - would have to look it up. I have flown through rain many times, always at 2700 RPM. It works and would not even think about flying through rain without it.

I am told the tape costs about 3 knots and I saw a reduction after applying it.
