jerry,i found that a product called araldite is perfect for that type of repair you can pick it up at the nearest wilkinson store
it come in a pack with two tubes one hardener the other resin
its about £3-4 quid if you dont like the sound of that you can pick up another one called tankfix this is used to repair petrol tanks again come in two parts good luck m8
