We bought our Bayliner 4788 in the fall of 2012, and had her hauled in May 2014 for bottom painting. Miss Maui took two coats of SN-1 at that time. We have a diver replace the zincs on our boat twice a year, and each time he gives me a bill of health on the bottom paint. Every time he replaced the zincs he was amazed at the lack of growth on our boat. I don’t know anyone at our marina who can go more than a couple of year between haul outs and bottom scraping. ePaint is a real performer.
