Sealants are modern 'waxes' are engineered to bond to the surface and last for months. Carnauba wax in any brand or form is a natural product and will only last for weeks (maybe 3-5 weeks) on a daily use car. Salt in winter will remove Carnauba right away.
My proven "Combo" is Klasse AIO + 3 coats of SG (Acrylic) then S100 (Carnauba)wax applied every 3 weeks. Phenomenal on the 354 silver. I get 6+ months of protection from the Klasse and the added gloss of the S100 which is the easiest paste wax I have ever used (mind you it smells like funeral candles).
