Re: SF Bay - how long do you get out of Pettit Trinidad SR?
I think when people refer to a coat and a half, the half is an extra coat applied to leading edges of the keel and other high-wear spots. So most of the hull gets one coat, high-wear areas 2.
We are referring to hard bottom paints, non ablative, which is what I have.
