Metal Polishing Myths, Half Truths and Lies

8. I want to protect my finish with carnauba so it will last longer

Sorry, Carnauba is acidic. That means it will attack what is underneath.

It is also porous. That means it will get oxidization going too.

Just as a bonus you'll find that it will probably increase pitting on road vehicles as well. This is because by putting a soft surface over your wheels, tanks or whatever - you are helping to guide the missiles in, just like with a full metal jacket (used on an armor piercing bullet). Or a fitter using electrical tape over the painted wing of your car so he can drill a simple hole.

Carnauba is great for show vehicles that are subject to regular repolishing, and useful for protecting from road salt in morthern climates. otherwise, leave it off.
