Leading Edge (Helicopter Blade Tape) tape is available from Demon Tweeks part No: 86741HS. It is 4 inches wide and costs £12.57 / Mtr.
I have used it on the belly pan of my BMW R1100s to stop stone chips etc and also have it on the rear / top of the tank on my 749S as a clear tank protector. Spray the surface of what ever you are going to fix it to with water so that it will slide, then work the water and air out from under, a hair drier on warm will help.
