Wellcraft Airslot hull repair

.....I have made similar repairs by opening up the area enough to stuff some fiberglass matting into the gash and then injecting epoxy mixed with fast hardener into it......add a little more each day until it fills the gaps completely...then sand it smooth before primer and gel-coat (or epoxy bottom paint)....check out some other opinions before doing this, there may be an easier method!
