ProsRetards LE corrosion.
Reduces LE erosion from small particles.
ConsInstallation difficult - could be improved by pre-slitting backing tape in 1/2" widths that can be progressvely removed as the tape is laid down.
Inevitable dings from large particles require splicing in repair tape - adds "hassle" and skill necessary to prop upkeep, but against increased longevity is probably worth it. Large dings "crater" the tape causing small aerodynamic spoilers at that point on the blade until repaired.
Small particles penetrate the tape, are prevented from dinging the blade, but get stuck as the tape closes on top of them, trapping them, and adding roughness to the LE at that point until repairs are spliced in.
LE appearance quickly becomes "cloudy" as tape suffers wear, but is aesthetic issue only, and tape does increase prop longevity.
