Try to make a claim under the so-called "warranty" and the valetter will refer you to AutoGlym who wriggle and give all manner of excuses e.g. "bird droppings not covered" but acid rains is!!
I have used Auto Glym products for over 15 years and found them very good but Lifeshine is no better than a good polish and costs you a great deal of money
In fact I am so angry at the irresponsible behaviour and misleading way in which AutoGlym has behave that I have now switched to Meguirs and find their products even better and a nicer company to deal with.
