Before going to the extreme of wet sanding...
You can try claybar, but if the print isn't just on the surface, it won't come up with that alone (oil prints).
The next steps would be the following:
First get a dual action random orbital.
Use some clear friendly compound (like meguire's ultimate compound) until the prints are gone. May need to lean into it a bit. Use medium speed. Wool pad.
Then use a ultra fine polish with the. DA orbital. Also medium speed... Black soft pad.
Then sealer/wax. I like to hand seal/wax personally.
