What is the best compound to use to polish the hulls. Is there a special way you do it. Buffer or by Hand.

Scrub with bon-ami, especially good for the textured surface on deck tops. If you think the gelcoat has wax on it, (and at some point someone probably waxed them) use a product specifically made for wax removal. Then you can wet sand (by hand) with 400, then 1000 grit sandpaper and then use a fine grit (automotive type) rubbing compound and a buffing wheel. Finish off with 303 UV protectorant.

Captain Dave has a whole bunch of past posts (H16) that are more in-depth. Jamie ZX as well.

Skip any steps you want, except wax removal, you'll grind the old remnants into the gelcoat.

What's wrong with wax?

Nothing wrong with wax. Some racers believe your boat may be faster without it. Use a carnuba or wax recommended for gelcoat surfaces, if you like. You'll need to apply two to four times a year, the 303 protectorant about the same cycle (maybe less).

I was describing removal of oxidation, which creates miniscule holes in the gelcoat, so sanding is more than likely necessary. Let me point out it's easy to burn through the gelcoat with a wheel so beware. Also, Dave had recommended a BASF auto product for wax removal.

Its probably too little too late but if you do wet sand your boat, clean your driveway or where ever you sand the boat IMMEDIATLY, I wet sanded my boat in my driveway, and let the water dry, and the yellow particles from my gelcoat pretty much absorbed into my driveway leaving a yellow spot.

Wet sand only the deepest of scratches to smooth out the transitions. Fill them with gelcoat if you want and sand them. Then get yourself a good buffer. Go to your local fiberglass or automotive paint supply place and get a product called Perfect it III from 3m. Get the "Extra Cut". This is what the pro gel coat guys use. It will take a lot of material off, so make sure to not burn through. The Hobie Gel is pretty thick, so don't worry too much. This stuff is abrasive at first, then breaks down to a fine polish. It's like an all-in-one; it will save you a ton of time! It will remove huge orange peel and years of oxidation. Give it a shot.

I used a pressure washer. Was amazed how effective it was.
