Double Action palm sander.
wet/dry compatible stick-on sanding pads.
Compressor.
At leat 5 feet of very flexible (flimsy) air line - stiff stuff can run from the compressor to the last five feet.
Start with 600 or 800, depending on what kind of trouble you are sanding thru.
Wet the surface, wet the sanding pad. Sand with medium speed, very light pressure. Frequently dip in water to keep chunks of dust from "bonding together".
1000 then 1500 paper. Now polish with a speedbuffer and light polishing compound.

Re: wet sanding / polishing ??
Wanting to go a little faster I’m trying to clean up a poorly done anti fouling paint job on the bottom of my 34 Scarab. It’s been there since before I bought the boat and am wondering what type of speed increase I can expect. Any ideas?
To your question - I had to scrape the bottom paint off mine, then sanded with 600, then 1500, and then I am polishing it with Flitz and then Meguiars color restore and then Meguiars wax. It’s working very well so far and looks great. It’s not hard to do but once you get started you’ll realize how big a job you’ve tackled.

As bad as that sounds, it's not as bad as you'll feel after doing the job yourself!!!
Actually, I did a 35 ft cruiser several years ago. It turned out great but OMG!. As mcollinstn said, work with alot of water, and in several steps until finished.

I would just have used 3M Perfect-it (white cap/the most powerful), then use the one with black cap, and then polish and was. You will be impressed of how effective this is. Sanding make an enormous job, and I bet that you will regret.... A true hell of a job and difficult to do all the surfaces shining the same. But sanding will make the best result if you do the rubbing well.
Good Luck!

I am only working with a small area. I want to remove the "fountain" logo that was painted above the rub rail. I was thinking that I could sand it off so that I can mount the chrome plaques.
