I know this is a loaded question but what is the best bottom paint/process money can buy?
The answer to your question is: LOCAL.
The waters YOU sail in and your FRIENDS sail in determines what is effective for that particular area. Your local boatyard and boating neighbors can tell you.
There is NO one-size-fits-all answer to your question.
When I lived in Northern California, there was one paint that worked for me and my neighbors, so we used it.
When I moved here and asked about paint, I listened and learned: the formulation is different, the water's colder, the environmental rules are different, and SO IS THE PAINT (that I will use in April).
Ask around.
Good luck.
