Sunlight UV Damage

to Paint on Cars

Clear Coat Thoughts for Modern Automobiles

Sunlight problems from ultra violet are getting worse now due to lessening of the Ionisphere from natural pollution, green house or so we have been warned. These UV rays can easily be protected with clear coats, ceramic coatings and a good wax job you car. If you were out in the sun and the skin on your nose started to peel or your eyes were becoming white blinded by the sun you would no doubt put on some sunglasses, a hat and perhaps some sun block. Today's automobile is ready and able to prevent this through its clear coating, but it must be cared for to do its job.

Swirl marks are caused by car washes or untrained auto detailers, which are too aggressive for the paint. Such swirl marks are etchings in your car's clear coat. They reveal damage to the paint. If you are waxing a car and wonder if you have damaged the paint, there are ways to tell. How can you tell when you have accomplished the task in waxing your car correctly thus saving the paint and creating a mirror finish? Take your watch and tilt it sideways and then upside down and it should look like a movie clip and then a mirror as you spin your watch with no distortion. You should be able to read the time in your paint by the reflection.

Another way is to take a fluorescent light and see if it is crisp or if you have any weird wave patterns coming off of the paint in the form of distortion or refraction of the light in any other direction except directly into your line of sight. Before going hog wild on the clear coat with Clay Magic or any other materials, check the clear coat width. These units are from the old plating industry and used in industry to test thickness of substances. There are small units used by art consultants and engineers; but in the auto detailing industry they use little hand hold units to check the number of mils thick a clear coat has left on it after battling elements for sometime. You can find them on eBay cheap. Only serious auto detailers carry these. A good clear coat is 5 mils or more, but most manufacturers use 2-4 mils and the substances are better than before. Color coats are usually 3-5 mils and primer coats are 1-3 mils. Aircraft use more one step paints to save weight and many manufacturers use less paint to save cost and save steps by using multi-step paints, some good and some not. Minor oxidation can decay paint about 1-1.8 mils. Surface scratches and shopping carts can cut through clear coat and half way into color coats, thus a filler wax is needed after treatment is rendered and do not take a buffer with a short wool pad to it either. I hope you learned something here today.
