I've bought some of that also, as it was recommended by Pete during the training morning to be used every 6 months on a ceramic coated car. Haven't used it thoughUsed the Gtechniq citrus snowfoam for the first time at the weekend, very impressive. I had been using Anachem which was great, but the Gtechniq just seemed to really get a lot of the dirt off the car before I even touched it, and the car was really dirty.
