Watch out for 'carnuba' verses 'carnauba' though. They are worlds apart in quality and results.
Carnuba is a chemical derivative (better living through chemistry-type) that is OK for cars, but will fog and generally be less than desirable on your bass body.
Carnauba is the true carnauba bean wax, which is very hard and is hard to keep in a paste, so it is ground and processed for a long time to get it to be a workable consistency.
Mother's is very good as is "Pro Wax" in the yellow can that has no abrasives. I really prefer the paste in the cans.
But lately I have been using
Meguire's Deep Crystal Step #3 Carnauba system wax.
It will never get so hard that you cannot buff it to a high gloss, unlike things like Simonize by SE Johnson. Don't use this stuff!
One thing I did was on a black acoustic bass that I bought used, it had a small dent on the side that I spit-polished with Kiwi black Boot polish like I did in the navy on my shoes and boots until they shined like patent leather.
If you do it right, it will fill the dent and it polishes off to a very good shine and you can put the carnauba over it later when it stops gassing.
I imagine you could use any color of paste shoe polish to fill dings and small scratches in just about any bass, since there's so many different colors of paste shoe polish.
Just FYI.
