Your RPO label will tell you which white you have Jr can help with this.
As far as wax is concerned, I normally use what the used car dealers use.....Liquid Glass. The stuff 'flows' to an even coat with heat, so I don't use it in winter, but on a car with virtually no clearcoat left, it'* amazing. Looks like a clearcoat. Nothing I've ever used before works as well. A day or two after you put it on, you can see the difference.
Very hard to find sometimes. About a third of my car was repainted in June (driver'* door, left passenger door, left rear quarterpanel, roof, and trunk lid). Liquid glass makes the old clearcoat match the new. Looks like the whole car was freshly painted.
