remove fiberglass

my walden broke and im going to make it into a wakesurf. I have a friend that will shape it and glass it for free. All i have to do is get the fiber glass off. Where should i start? The tail is broken so it leaves me 5'5" to work with

Parker,
Just take a nice sharp utility knife and cut along the outside of the rail - it is OK to cut through the foam a bit since you will be probably shaping that down anyways. Once you've cut all the way around, you should be able to peel the fibgls off the foam slowly and carefully. you will probably be getting little chunks of foam here and there, but again, if you are reshaping it into a wakesurf, I assume you'll have plenty of foam to work with. good luck
