If you're using a traditional buffer be careful of decals and upholstery and rubrail, you could potentially burn them.
I just did my boat with a porter cable dual action 7424 with a yellow buffing pad and a somewhat aggressive compound, PoorBoys 2.5. With the dual action I didn't have to worry about burning the upholstery in the areas where the upholstery butted up to the hull or rub rail. Probably could have gone a little more aggressive with the compound but the boat feels like butter.
