Obsessed Garage is proud to offer Gtechniq's detailing products. All of my pro buddies kept telling me Crystal Serum Light. Finally when I got my hands on it, put it on the red R8, then ran my the back of my hand on the paint afterward, I instantly knew after all this decision making that this was the coating. Top CSL with EXO v4 and treat with Bead Maker regularly, and we have it. There are lots of great coatings on the market, but I don't want to be a retailer. I want to offer you the one I use. This is it.
