bought some smart wax and sealant and shampoo.very impressed with results.better than auto glm.wash first,wax,then sealant on top.not cheap but worth it.works awsome on sat black,,,water still beads great after 5 wks and easy to remove watermarks after washing.

i think Smart is the brand name of some stuff my local autospare shop sell, I bought a 'Smart'quick wax spray to use as a lube when claying the car, works well a spray on wax which i use when drying with large microfibre drying cloth as a final touch Former Mod/Member, with the most post & Chicken George Arch nemesis
