I got this straight from the staff at Griot's
Best of ShowDetailer is positioned as Griot’s Garage premier spray detailer. Our long heritage of offering one of industries best- Speed Shine, combined with our “Take the best that exists and make it better” mentality motivated the creation of Best of Show Detailer.
We’ll always offer Speed Shine as it is one of our best sellers and beloved by many, in addition to being our only recommended Spray Detailer for use as clay lubricant.
Best of Show Detailer is designed to maximize your color, depth & clarity to any painted surface while safely removing light dust, bird droppings and finger prints. It can be used in direct sunlight, perfect for the car show environment and has an ultra-fast wipe off in any temperature.
If additional performance characteristics come into play…
With a standard microfiber cloth, Speed Shine requires an initial wipe, with a flip of the towel to flash. Hence, Best of Show Detailer will deliver faster wipe-downs in wider ambient temperature ranges.
Additionally, Speed Shine should be used in the shade on cool surfaces
