*mada: QD's are generally used for cleaning the paint, whether for using it to clean contaminants like Tree Saps and Bird Droppings before it etches into the paint or simply for removing light dusts and giving it that newly detailed look. QD's are generally used on a dry surface and personally i use after i wash my car when im not waxing, if im waxing i use it after the waxing stage. You could use QD's for after washing just to add gloss but it does not offer any real protection. As for your Eagle One question, it would depend on what product you bought, is it the Wax As You Dry? Wipe and Shine?
