Are you talking about the purple "Instant Spray Wax?" Formulated with Zonyl® only by Dupont? Made by car buffs for car buffs? Made by the FINAL DETAIL Company, Inc. of Moorestown, NJ?
Never heard of the stuff.
So, any more detail? Did it add gloss? Depth? Mirror-like finish? Any thoughts on how long it may last?
Meguiar's used to make a quick detail spray called Final Detail. It was my favorite QD for a couple years. FD was replaced by Last Touch for VOC compliance.
