Once you get it polished up right with Nuvite or Rolite etc. then you just wanna keep it protected with a good polish. IMO California Customs "Purple" is the winner hands down. The Purple has a protective polymer in it and will keep you safe from things like salt air etc. After getting super dirty and dusty I just wash my plane with clean water and wipe dry, looks like I just polished for two days
I use a cheap orbital buffer with microfiber cloth, takes about 8 hours n at least 4 beers to get the job done solo, once or twice a year and its good to go. Good luck with trying to keep people from touching it and wanting to smear their greasiness all over it, look but don't touch dammit
