West Marine has a good selection, not sure if their prices are competitive. Check under "Boat Maintenance Marine Finishing"

The first item Starbrite Premium Polish with PTEF. The PREF keeps things slippery, & helps to preventlake goo from adhering, seems to work fairly well.
The fellow mentioned above uses the 3M Finesse it II product...ouch when you see the price. It works well to remove light oxidation. According to their product intel, the particles break down into finer substrate as you use it, effectively changing to finer grits.
If your boat is heavily oxidized, start out with something like 3M Super Duty Rubbing compound, to remove the oxidation, then follow up with a Polish/Wax. You're now seeing why a variable power polisher is de rigeur
West Marine used to sell their own branded rubbing compound. They don't make their own, so it's probably from one of the major manufactures, rebadged. It's probably still there, on one of their pages. IIRC, it was priced very well, & most likely works as good as any rubbing compound. You just have to decide what level of oxidation you are working with.
Pick up some polish/wax,(you will eventually need it), & try a small section that is most heavily oxidized. If the result is satisfactory, keep on going. If it takes a ton of work, & repeat application, then get some compounding product & resign yourself to a 2 step process.
It is WAAAYYY easier if your boat is apart. With the hull on its side, you can do an entire side in under 30 minutes, without any fatigue.
You have a Dart...no tools required, they have to be the most user friendly Cat to assemble.
