To repair the crack along this customers deck on his jet boat, we first went about removing the black rub rail strip around the outside of the deck. Once removed we could go about grinding out the gelcoat and delaminated fibreglass behind the crack in order to remove all of the structurally weakened area. Because the delamination had not travelled right through to the inside of the deck, we were able to complete a single sided repair. We went about building the ground out area back up with fibreglass, before completing the filling and fairing stages. Being an older yellow boat, this colour match was rather tricky, but with a bit of fine tuning, we managed to get the best result we could have hoped for.
