not a hard fix. you need to grind a groove along the crack, basically just give the crack some depth. go to your local autoparts place and pick up some fiberglass material and resin and follow the directions. maybe try some on a spare piece to learn a little. the fiberglass sets in about 15 min. I would place the mat on the underside of the fender and pour resin into the crack on top. finish with bondo. good luck
