Excuse me if the picture don't seems otherwise (Turning brown). I used my latest iPhone 4S. Trying it out........not bad after all. However, the middle part and side of the apple does indicates it has turned brown.
Oxidation can also be a problem for car owners, since the outermost layers of paint are constantly exposed to air, rain and sun. If the car's outer finish is not protected by a wax coating, the oxygen molecules in the air will eventually start to interact with the clear coat or lacquer. As the oxygen burns up the free radicals that's contained in the clear coat, the finish would then becomes duller and duller eventually. Restoration efforts may include the removal of several micron layers of affected clear coat and the reapplication of a new layer of wax. This is why professional car detailers would recommend at least one layer of wax to be used, every time the car is washed or to be applied periodically. The secret of preventing oxidation caused by oxygen is to provide a layer of protection between the exposed material and the air. If the surface is quoted by a layer of wax then the surface has very little chance of experiencing the destructive nature of oxidation.
The real issue I believe that many of us should know, is paint surface treatment. It simply means, without having to deal correctly with the clear coat, there is no point having to apply any wax on the car.
So, the conclusion is .............we want to share with you why we do what we do !
Stay tuned:)
