Most Autopians will probably recommend some type of true (NOT a spray) ceramic or graphene coating. Depends if like to wax or seal your new SUV on a "more frequent" basis with what you have on hand OR if you want to make the (sizable) investment in purchasing said coatings and then apply them and sit back and enjoy much-less laborious vehicle appearance (exterior detailing) maintenance requirements.
Black is pain to keep clean and looking good, but you knew that going in.
My suggestion? Look at
Merlin`s Enchanted Concours Wax for your black SUV. It`s a hybrid (there is a marketing buzz word!) of both the "wax" and "coating" worlds
