It's going to look fantastic, but cleaning up all the compound splatter is going to be a real chore. I never went beyond 2000 grit. I tested it and found that at that point a good fine compound would remove any scratches left from the sanding. I always machine buff using Meguiars No. 9 fine cut polish followed up with their swirl remover on a foam pad. Use a different pad for different compounds. That was my system on solid single stage colors. Clear coat may be different.
