Swissvax Onyx
Been using this for quite a long time now, ever since i went to a Swissvax detailing day at Knaresborough, North Yorkshire. Really easy product to use on and off, lasts about a 3-4 weeks before the need for reapplying (If your car lives out in the elements). I tend to find that you get better results and it lasting longer if you can leave it on for 24 hours before removing. I tried this out for the French car show, Expo and TRAX events this year and really does look well. You can leave it 10mins or as long you like till you wipe it of its totally up to the user. I find a pot of this last around 2 years. I do 2 cars every month with it so value for money when you look at it in the long haul is quiet cheap.
