Great! With the pad recommendations, I suggest 5"-5 1/2" pads.
Oddly enough with the Flat white and the metallic blue, I might suggest different Last Step Products (LSP's)
I'd go for different "looks" in those two colors.
The flat white...my first thought would be plain ole'
Collinite No. 845 Heavy Duty Insulator Wax
IMHO this is a very underrated wax. It has been called the "Rocky Balboa" of car waxes.
Coli 845! Great longevity, durability, a bright shiny sparkle, and a great "winter wax".
Metallic blue...What are you looking for? Depth, warmth, metallic pop. longevity, durability?
Have you considered a ceramic coating?
