You can never have too many valeting products,it means youve always got an excuse to play with the car! Ive always found Autoglym to be consistently superb,whichever product. I own my own valeting company,and ive tried virtually everything on the market,but for ease of use,end product,and a finish that last's,Autoglym is definitely one of the best. I find that if you polish your car with Super resin polish,you should leave the polish on for about 30 mins,then remove with a microfibre cloth,finally treating with Extra Gloss Protectant-leave for about 2 hours-usually looks mint!
