The Bag Test Even new cars that have been sitting on a car dealerships lot for a few weeks can accumulate contamination that bonds to the paint surface; it shouldn't be assumed a vehicle that looks good is contamination free. Here’s a simple test that will indicate whether or not you need to clay. Wash and dry your vehicle, put a plastic sandwich bag over your hand and lightly rub your fingertips over the paint. If it feels rough or you feel little bumps or protrusions every snag you feel is a surface contaminant that the clay bar can remove but you may not be able to see, especially on white or light colour vehicle surfaces. Detailing clay has made a huge impact in paint finish care because it removes oxidation and allows the paint to remain healthy, longer. Applying a coating over a paint finish does not stop oxidation; it only slows it down. Using a chemical paint cleaner is better for your paint finish; because they strip away some oxidation and allow the coating to obtain a better hold (anchoring to the micro-fissures of the surface) and lasting longer to retard oxidation. An extract from one of a series of unbiased Detailing Technical Papers, a library of educational materials that has become the #1 reference for car care on the Internet Chances are you'll learn something about detailing if you read any of these; although these articles will not improve your detailing skills, lead to a successful business or change your life. Applying what you learn from it, however, will. That's where your commitment comes in - you need to make a commitment to yourself right now that you will take action on what you learn. © TOGWT ™ Ltd Copyright 2002-2010, all rights reserved
I have noticed the cheap fold over at the top sandwich bag works best. They are a lot thinner then the ziplock style. A cigarette pack clear wrapper will do in a pinch. Paul S
