Any fender, no matter what it’s made from, can be grazed or punctured.  We recommend you use Hauraki Fender Covers to increase the graze and puncture resistance of your fenders. Due care should be taken when positioning fenders.  Ensure the fenders will not come in contact with any surface or object that could cause damage to the fender (such as vent covers, nails, bolts, rough surfaces etc).
