I've done the Mainesail polish/wax treatment twice on my prior C250, and just a week ago on my C34mkII. It gets easier each time.
He does give some options on which materials to use, so I'll briefly describe what I use.
I really like using the Presta Ultra Cutting Cream for the polish. It starts as a course grit, but breaks down into a fine polish as you work it in with an electric buffer with wool pad. This gets you a nice shine in one step. The 32 oz bottle is costly at $30, but lasts a long time. I've done my C250 (twice) and 34mkII once, and still have a little left over. I also have the Collinite Liquid FG Cleaner that I use for hand-polishing intricate areas, but for a large smooth surface I prefer the Presta with electric buffer.
Make frequent use of a spray bottle with water to extend the open time of the Presta and provide cooling. If it dries out, you may damage the fiberglass due to excessive abrasion and/or overheating.
For the wax I have used Collinite 850 Fleet Wax. If you have done your polishing correctly, it should be wipe on/wipe off without any electric buffing required. If it's hard to get off, you're waiting too long, doing it in sunlight, and/or did not do a good enough job polishing. This year I used up the 850 and needed more on short notice (not enough time to order online or drive all the way to West Marine), and the guy at the nearby auto refinish store told me their 476s is the same stuff, just packaged and marketed for the automotive market. So I bought some and it seems to be the same as 850. Collinite's application tables suggest that it's the same stuff as well (same balance of properties). So if you want to support your local business, I'd suggest considering the 476s if your Presta dealer also carries Collinite. One advantage of buying locally is the ability to return unused material, which came in handy when I didn't end up needing that new bottle of Presta.
For my bootstrip restoration I have always started with a wet sand on the blue gelcoat bootstripe, followed by the Presta and wax. Don't overdo the sanding. You will see some light blue residue during the wet sanding. If your bootstripe is painted, all bets are off and you should be very careful. If the paint is Awlgrip or other 2-part urethane, I would only follow manufacturer's instructions for polishing.
I've used Poliglow on other boats, and have very mixed feelings about it. I'd always recommend the Mainesail procedure, and only resort to Poliglow if you find it impossible to get a truly glossy, non-porous finish by that method, or the hull form of the boat is too irregular to use a mechanical polisher. The former was the case with our Phantom sailing dinghy, and the latter was the case with our Trophy fishing boat. Polyglow worked well for those cases, but the Mainsail procedure gets superior results that last longer.
