I loveeeee carnauba. I have Adams Americana and Shine Supply Signature shine. Gahhhh they are both amazing the smell the feel and the glow is great. I'd give the slight edge to shine supply but that may be cause I have used it more recently. It goes on insanely smooth. Some Sinatra and a tub of Sig shine and I'm on a different planet. You don't get that kind of experience with sealants. But of course I have a few and I always use them as a base layer.
