How to prep Fiberglass Boat Bottom and apply VS721?

Skipper May 1, 2018 News

I have a 22′ deck boat. I would like to try VS721 bottom coat on it. My question is how much do I need to purchase and the same for anything else I need to prep for it? From what I’ve read, I should also get Boat scrub. Is there anything else needed to make the VS721 last the season?
Also, can you put VS721 on by hand or would you recommend using a buffer?
