I use 3m too, any paint shop will have it. Those are more for after sanding though or trying to cut out scratches and swirls. For regular waxing I use meguiars carnauba wax on a wool pad to apply and foam egg crate to buff out or just a microfiber rag. After I pull the boat out I wipe it down with meguiars #7 glaze with a couple of microfibers.
