hull repair question

Well, the damn river did it again. This time instead of replacing the prop and rudder, I need to do some hull repair. I found a site with some info on how to patch (http://capndsboatshed.com/hullrepair.htm) and I was wondering if anyone had ever attempted a fix. Luckly, when we hit we were barely moving forward, so the extent of the damage is minimal...just some chips in the gellcoat/paint, and one spot where the fiberglass is exposed. Nothing structural (ie, no holes through the hull) just cosmetic stuff. The spot to repair is in the front of the V, the first point which would hit something underwater...dead center in the spine. Any pointers would be appreciated.
thanks,
