Waxing the boat

[340DA]

I have a 340 DA that I am the 2nd owner. The previous owner had it waxed evey year so it is in great shape. I want to continue having it look pristine. The boat has one season worth of oxidation above the rub rail (light amount, not bad at all). Shine below is perfect.
How do you recommend I clean it and wax it to keep get the mirror image shine?? What polisher? and should I use a random orbit buffer?

I've heard good things about 3M cleaner wax. Remember to polish after ;-)
