I think it is the same color. I know that 78U is the Aurora'* pearl white, but why not have one number before it be cherry? Makes sense to me!
The wax I used is Meguiar'* Cleaner Wax. I'm considering going over that with Caranuba shortly. Of course, pictures will be available shortly after. You should definitely use a cleaner wax, wait a few hours, and then add a thick and delicious wax on top. Mother'* Caranuba is fairly widely available, or you could splurge on a Menzerna bottle, available online.
