The antifouling paints for aluminium boats need to be specific for the aluminium structure.
There needs to be a compatable expoxy primer applied first, with most products.
Be careful that any antifouling paint
used is approved for aluminium.
Seajet is a large company that makes many different types of paint
and have not used any of their products.
Likewise Chugoku, although I have never even heard of them.
