3M makes a really good wet sandpaper. It's measured in microns instead of grit. I believe it's a synthetic material, i.e. the abrasiveness is very consistent, producing a very consistent finish. It's extremely durable, the backing being made of some sort of plastic instead of paper. You won't tear it by hand.
If the scratches aren't too deep, I'd start with wet 30 micron, then 15. From there you could use the rouge if you choose. Sorry, I don't have the first idea where to source it, though. Maybe an autobody supply place? I used it when I fabricated solid surface (acrylic) counter tops.
