I read somewhere else that the sealant is used against the bare clearcoat, and then wax is put on ON TOP OF the sealant. Are we talking about two different kinds of "sealant" then, or was what I heard backwards? Sounds like here youre referring to the sealant as a final step product.

Also, what college offers a masters and PhD of Detailing, anyway? Because, Lordy, there are quite a few details to get worked out, ain't there?
