In the initial post Styria asked;
'Firstly, Panel Beater's clay. Those who have used it will more than likely testify how, so cunningly, it can remove surface impurities in paintwork. Sure, not as good as a 1500 cut-back and buff, but nevertheless a great product to use. The question I have is this: Does it, after SEVERAL applications, over a period of time, affect the basic quality and durability of your paintwork ? I have been told that it doesn't, but would be grateful for further qualified and informative opinions.'
I had a look at the Zymol website and here is what they say;
'Acid rain, road silt and fallout are the enemy of paint. Water and zymöl Clear wash away the loose particulates but not the embedded pollution. The sun acts as a catalyst to help these paint-toxic pollutants penetrate and destroy your paint. Lehm-Klay, a Professional natural cleaner and conditioner for automotive paint, is a superior remedy for acid rain etch, moderate abrasions, bird droppings and light oxidation. Lehm-Klay removes marring and soils through microscopic polishing and cleaning without harm to new or old paintwork. Important: zymöl Lehm-Klay is a Professional product and is designed to provide maximum results with minimum product application, use gently and only for emergency service.
Ingredients:
Naturally derived and produced from Kaolin Clay from Africa and Chalcedony Quartz from North America.'
I know that does not fully answer Styria but it does point us in a particular direction - 'use gently and only for emergency service'
