I don't plan to use my M2 as a daily driver, but rather on the weekends only, putting less than 1,000 miles on the car annually. It'll be garaged. Have you given thought to recommendations made by The Wirecutter:

- Nu Finish Liquid Car Polish,
- Nu Finish Soft Paste Car Polish, and
- Meguiar’s NXT Generation Tech Wax 2.0.
