I had long been using Micron CSC in for my boat in Key West. Several years ago I tried bottom paint made by Sherwin Williams. Yes, Sherwin Williams. They have been making paint for the Navy for some time, and I decided why not. They have a "hard ablative" paint that has excellent anti fouling in Key West area. It is firmer than the petit Vivid paint, It does not come off in a cloud when you wipe it down, I usually use a terry cloth towel. I get about 2 years + or -. Per painting. The main wear point is at the waterline so extra coats are applied there. I am sold on the Sherwin Williams paint.
