Have been testing this product for some time now along with their lubricant called Speed Shine. Have been getting only excellent results on all types of finishes. The price of the clay being a eight ounce bar sells for $19.00 & you can get many uses out of just one bar. Prior to storing the bar back into its own round plastic container, you just simply spray on the lubricant into its container to keep moist & to also make it easier to remove from it's container.
The Speed Shine acts as a lubricant such as Meguiar's quick detailer. The cost of the Speed Shine 35 ounce sells for $9.95 & a little spray goes a long way. These two products go hand to hand together & I am very impressed with all of the results that I have seen.
In my personal opinion, this product has given me the best results in a product for a long time. It takes a lot to say that for a product being this superior in the short amount of time using it. I have done six vehicles with just one bar & still have been getting good results. I want to see how much life is left with this same bar that I have been using. It seems to still cut the amount of fallout along with jet fuel off the each vehicle it touches.
