Well, you picked the right time to do the painting. I noticed that bottom paint's on sale, at least at defender.
I have a couple of suggestions. We used InterProtect 2000E Epoxy on the bottom of both our sailboat and Journey On. Good results, since we had no blistering. Your call.
As to the bottom paint, we used Petit Trinidad with good results on the sailboat. Then we shipped the boat from San Diego to Mobile and it was out of the water for 3-4 weeks. The bottom paint peeled off in spots. Also, we had to grind the residue off, since we had put on several coats of Trinidad over the years, and the residue can only build up so thick. I'd get an ablative paint that can be out of the water. A lot of C-Dory owners use Micron CSC, but I'm sure Petit has an equivalent product.
