Can’t help you with carpet, that’d be work that I’d hire out.
Re buffing the gel coat, here’s what I do on my Wellcraft.
1. If you don’t have one already, get a variable speed polisher. I got one at Harbor Freight, if you use one of their 20% off coupons, I think mine was $25. Totally worth it and in fact, I don’t think there’s any effective way to do it by hand.
2. The oxidation is part of the gel coat, so it isn’t like the paint on a car. To polish out oxidation, you are removing a thin layer of the gelcoat. Therefore, start with the least aggressive polishing compound and only move to more aggressive if you have to.
I only use McGuires marine compounds. Fleet sells them. My suggestion is:
– Start with a #45 polish on an area like the transom that doesn’t show much. Follow all instructions to apply compound and to buff. BE SURE TO USE THE RECOMMENDED BUFFER SPEED!
– Keep the buffer moving. Up/down, side/side. Don’t pause and don’t apply too much pressure. Let the product do the work.
– Use a very bright light to check the results. If the #45 doesn’t remove all the oxidation and the finish isn’t bright, move to the #49. When you find the right compound, you’ll know.
– Stay away from the sides of the boat until you you know what you’re doing and get your compound selection right. It takes a little practice, so do the transom or lie down underneath and do the hull first.
– After it’s all buffed out, you still need to wax it or it will quickly re-oxidize. Yes, it’s a PITA. No one ever said boat maintainance was easy or fun.
