In terms of swirl marks, a sponge will make a difference... I noticed a huge difference on my old Petrol Blue Fiesta.
I think my spec list for FCS is currently going:
Wash (2 buckets, wash mitt and probably Meg Gold Class).
Doesn't need claying, but might do the front and lower sides...
Dry avec MF.
Clearkote Vanilla Moose Glaze.
NXT, maybe x 2 as per Rich's instruction.
P21s
I've then got Quick Detailer for intermediate stops on the Saturday and as an option for the Sunday if the car's looking good still...
