I'm currently polishing a 2006 Bullet that I believe was brought over to Washington state from Hawaii on the deck of a fishing trawler. I'm having to start with 220 grit. So far I'm only going to 600 grit and then to Rouge on a sewn polishing mop. It's a big job. The sanding is done wet with just a touch of dishwashing detergent in the water and a sponge to back the paper.
