The paint finish on the VFR is gorgeous... I'd hate to scratch it up. Mind you, when I ride the VFR my knees don't touch the sides of the tank (cover) but what the hell... it was cheap.
I used warm water with dish soap and a spatula from the kitchen as a squeegee.
Dunk the film in the soapy water and position it carefully on the tank. Lots of liquid lets you move it around and get it in the right spot.
