Your M3 looks amazing, post more of the bamboo. Enjoy in good health :cheers:
As for the paint, they are in fact paint marring/washing swirls. May or may not bother you, Zaino isn't going to help remove those if you do want to fix them. Detailing is a decease, and something I really wish I didn't get into. Just pay a pro and get it done right and be done with it. Let me know if you want help finding someone good in your area..
