This is 3rd week of November and this is the least growth I've seen. Enough to slow the boat down but no mussells or barnacles(they were all on my prop I found after I thrust my bow over the dock a week ago,...). Aquaguard was the cheapest last fall as well. I bought a gallon and just realized looking at the can, I still have a third of it left(I wonder if it will be usable next spring?).

It went on easily and a bit smoother than previous water based I've tried. After a power wash, it looks ready to go!
