Planning on bringing the Superboat into the shop next week for a 300hr service and also to wash, polish and wax. Last year I used a traditional wax which held up well with the monthly wipe down of speed shine.
I use a pneumatic orbital buffer for the task. Is anybody using any of the ceramic “waxes” and if so what brand and how are they holding up?

Performance Boat Candy is my favorite.

What is the best DIY gelcoat sealant/ceramic coating to use on a performance boat?

check this thread in general boating post. Lot of information/ opinion.

I did DIY ceramic coat (not wal-mart or big chain auto store junk) on the transom and keel area a few years ago. No more issues with water line stains etc. Holds a shine and I don't have to buff/wax minimum 2 times a year. I do keep it under a full mooring cover on a trailer and the reminder of it is vinyl wrapped. Only portion that gets wax is cockpit interior but probably going DIY ceramic coat on that as well. Also DIY ceramic'd 3 cars and walked my mom and step father through doing theirs with fantastic results.
