When i was at sanfords we applied a 4 year paint system to the hull i cant remember all the technical bs but the base was black like a tar then applied the base coats and finally the top coats
2 pot Enamel paint i think it was, it might work ok on aluminium allowing the paint to flex a bit with the hull it was Altex coating paint. @Pengy give altex in Tauranga a call they would be best qualified to answer your questions.
