Re: aluminum hull repair

You need to get rid of ALL the silicone first..... Nothing sticks to it and essentially it sticks to nothing properly.

Gluvit may be applied on the exterior but it will not flow against gravity.

You should do the repair properly.

Unfortunately I think you'll be wasting time and money by just doing the outside. Best of luck though.

On my little boat (12' aluminum) I used Gorilla Glue where the aluminum on the transom meets the aluminum bottom. Gorilla glue expands once applied, it can creap into the crack and seal it, worked great for me. I would agree that the silicone must be completely removed first.

Do not over apply, if you do remove excess before it sets. Once dried it is like concrete. Also Marine Tex is a great product.
