I am awaiting delivery on a brand new car. I have instructed the dealer to have their new car prep guy only remove any protective wrapping or cover on the car when it arrives but not to wash it or apply any type of wax or sealant. I will do that myself. I am on the fence now between using Turtle Wax Pro Graphene or TW Hybrid Solutions Ceramic. I will most likely clay bar the paint first.
My question pertains to washing the car as part of the process. Should I use something like Dawn DW soap to gently hand wash the car to make sure the paint is free of any contaminants, clay bar the paint, and then wash again with Dawn to remove any clay residue prior to applying the Graphene or ceramic coating product ?
Or is regular car wash soap that isn't a "wash & wax" product fine for the wash stages ? I have some Meguiars Gold Class car wash soap that I normally use.
