I use one gallon per hull
and a gallon to go around the waterline again and other high wear areas. I have a 47 foot cat. I had three gallons arrive at my house two days ago. My boat is about half prepped for painting, hope to finish prepping this weekend.
I use SUPER SHIP BOTTOM out of Florida
, they ship it directly to my house. The paint
has the highest copper content allowed , I have used it for over ten years now.
