Just figured I'd provide an update on the Griots. It has been a little over a month since I washed the truck and applied this product. It was long overdue for a cleaning so I dedicated my Saturday morning to getting it cleaned back up. The hydrophobic properties and water beading tendencies are still incredible. The truck is my daily driver, is not garage kept (will no longer fit lol), and has seen probably a half dozen rain storms or afternoon showers since I've applied the Griots. The product reacted almost exactly the same as how it did right after I first applied it. However, the passenger side fender seemed to be the only area that I noticed inconsistency. The product appeared to be pretty weak in that area. I'm not sure if this was an application error on my part, or if the Griots failed on that panel for whatever reason. But once again, that was the only spot on the entire truck that I noticed a change in performance. I reapplied to that fender and will continue to monitor the entire truck moving forward.
Now to the really impressive part. Others in this chain have mentioned how well it repels contaminants and how easy this product makes it to keep your vehicle clean. After 1 month in, I see that statement to be completely true. From driving in several rain storms over the last month, My tires had slung dirt and debris all down the lower sides of my truck. I always pre-rinse my vehicles before hand washing or using any soap. To my surprise, nearly all of the grime came off during my initial rinse! It all ran right off the truck leaving behind almost completely spotless panels. I had no difficult sections during the wash. What little dirt that remained from the pre-rinse came right off once I broke out the soap. I also noticed that drying the vehicle was considerably easier than usual due to the product shedding water so well. I typically have to use two drying towels on the truck and I was actually able to get by with only using one. I wish I had some pictures or a video to back up my claim but I didn't think about it until well afterwards. I will continue to update my experience with this if I find anything worth mentioning but at this point it is still a 5 out of 5 for me.
