I used to use Zymol which was a polish and wax combination on the hull above the waterline. It worked well, one step apply and remove, and held up all season, but I cannot find it anymore.
Also looking to buff out some minor scratches from docking, etc (ahem,) the zymol was good for this too worked like a buffing compound in that respect
Last year I tried Nautical Ease which was a 2 step cleaner then protectant and while this worked OK it did not last.
What are you guys using and do you like it?
