X2 on Griot's products. I use their Orbital polisher with "Complete Compound" then their wax. I sent Griot's pictures of my coach, the concerns I had, and asked for their recommendations on compounds, waxes, pads, etc. They have GREAT customer service and walked me through every question I had. They are expensive, but the best products I have found. It's a lot of tough hand work, but you get out of it what you put into it and the results are beautiful.
Best of luck.
