magnum- On a white vehicle I' *definitely* clay it. If you don't you could get "rust-blooms" from ferrous contamination. Not only do they look bad on white, but once they get established they can be very, very difficult to remove. Best to clean things before they get started.
When you said "Cleaner Wax Step One" did you mean the Step One Cleaner of the Deep Crystal system? OR did you mean another Meguiar's product that's actually a cleaner-wax (the DC Step #1 Cleaner doesn't have wax in it)?
I really don't like the Meg's Deep Crystal sytem as there are better approaches that are at least as easy to do. But as OTC approaches go I suppose it's not a bad choice. IF it were mine and I *had* to use OTC stuff I'd consider using Color-X instead and topping that with the NXT.
But then if it were me I'd find some Collinite 845 Insulator Wax instead of the NXT (it's available OTC in some areas)
