Cutting slits in rear fender to roll?

[Farkel]

Hmm I was thinking that cutting slits and then folding up individual sections would be easier

I heard some stories about Dimples appearing above/around the fender after people used the baseball bat method :S

I don't see how bending the inner lip of the fender could actually produce dimples

Pull the wheel off.
Get a hammer
Get a piece of wood.(Small section of a 2x4 works fine.)
Lightly tap hammer on the inside edge of the fender lip to get it to start to bend up.
Once it starts to go, put the piece of wood on it and hammer against the wood.

Repeat on other side.
Done.
