Bazza. one thing about Altex (and probably most other paint companies) is that the price of marine labelled paint is a lot more than the virtually identical product sold for industrial use. In the case of Altex, the industrial paint name is E-line 379. My boat is painted with that, very good results. Also, as a Tauranga resident, if you go to the factory shop, out the back, they have a pile of mis tinted paint, which is seriously cheap. There is a very good chance that there will be a colour that you want. Most of my boat is done with that stuff, and it has saved me hundreds.
