Thanks for the response. I saw that Brightside finish is not marketed for below the waterline but also wonder if boats that are used the way I use our boat requires below-the-water-line paint. For instance, I have the impression that the boat was made with the same finish above and below waterline but I could be wrong about that. I suppose I am mostly wondering if anyone has any experience putting that Brightside paint on the bottom of a boat that is used like ours.

If you're sure you do not want any antifouling protection, you might want to consider Interlux VC Epoxy instead.
