NANOSKIN Glide is the product we use for Step 3 of the decontamination process. It is our lubricant for either the Clay Bar or AutoScrub. I'm not sure how many years I've had my original AutoScrub pad, but it's more than 5 years old. So despite the initial expense, these last a really long time. I've certainly spent more on clay bars over that time frame than I have on this. I equate this to being about 90% as effective as clay, but much quicker and easier to work with. NANOSKIN is an essential part of my decontamination process.
