the best way to use ablative is to use a barrier coat then a coat of hard bottom paint followed by ablative. if you use a different color for the hard bottom paint the you can see where you need to touch up the next year. it's alot of work and a little expensive in the beginning to do it that way but end up being less in the long run as you only do touch-ups after the first time. also leaves you some protection if you wear through the ablative.
