You don’t say where you’re at, but if you’re in any type of sunny climate, I would forgo carNuba and put it on the sealant of some sort. It’ll last much longer, it has exactly the same or better gloss, and it’s a bit easier to apply. CarNuba down here in Florida last weeks during our summers, I don’t know anybody that uses it anymore. Wolfgang deep gloss sealant is a favorite here or a new player: 303 graphene spray sealant. My single 303 application is going on 4 months and it still looks brand new. Beads like crazy
