I know the Blackfire listed above is pointing to its sealants. By Carlack do you mean its carnauba wax?
Not to confuse you in any way... If you're going with a wax/sealant combo and instead of carlack carnauba (which is also great), why not go for blackfire midnight ivory carnauba wax (aka blackfire wet ice over fire combo)? Products from the same line offer best bonding/compatibility/looks and both these together are considered one of the best combos as well.
I know this combo is more used for the midtone/darker color ranges but both of these dont bring any color darkening effects for them not to be usable on lighter colors and I've seen several detailers (on intl forums) use this combo on lights as well successfully.
Guessing from your dp, is it for white color car ?
