That's my main issue. I walk like a penguin so I also hit the stays with my wonky legsOh yeah, my heal either ripped off or rubbed through the stuff after two rides.
I also found some bubbles on the first sheet I did...and a cat hair dammit.
MOAR lubrication is better. I made an absolute mess in the kitchen doing it, but it helped. So did beer(s).
Even though it was a right pain, I think I'd do it again.
