I have the Lifeguard Scratch Removal Kit by LifeGard Aquatics way back when and it goes up to 12,000 grit. Here's a pic of the kit. Hope this helps

If using a machine to buff things out, I would go to at least 6000 grit prior to using the machine buffer. Heck, if it were me, I would likely go up higher than that just to minimize the polishing effort.

I would suggest going to youtube and finding some videos on color sanding and polishing automotive paint. Particularly clear coat safe processes. You don’t need to use the Novus system but Novus, 3,2,1 work well too. You ultimately kind of want to treat it like a car paint and the higher the grade of wet sandpaper you use, the less effort required during the polishing process. You can get micro mesh sand paper all the way up to 12,000 grit.
