ok mga yan bro, i have 845 too and maganda rin effect niya. ang carnauba wax at sealant bro ay magkaiba, although pareho silang last step product at parehong function as paint surface protection. carnauba based wax gives more gloss na natural effect o parang wet look shine, while sealants are synthetic waxes kaya typically gives mirror finish type of shine. pero para sa akin pareho lang

any of the two are good last step products (or LSP) naman that gives protection sa paint. mas durable nga lang ang sealant, thats' the reason why ginagawa ng iba pinagpapatong. rule of thumb is sealant, cure then wax. ok din mga spray waxes, they are very easy to apply, i used it in between washes to maintain yung gloss.
