The Sun Wreaks Havoc on Car Paint (and more)

shadesMalaysia is hot, so are most places in the summer.  What happens to your car and your car paint in this heat?  Many think you can fry an egg on your car on a hot day.  You can try, but who would want to fry an egg on a car. But, this doesn’t mean it isn’t hot.   Leaving a dog or a child in a lock car can just destroy your life (jail time anyone?)  Ever sit down on leather seats wearing shorts or a thin dress after leaving the car out in the sun for an hour or two…ouch!)

Overall, the sun can cause problems to your car paint, your tires and to the inside (don’t eggleave pets and children in a locked car in the sun.) That doesn’t mean it isn’t hot.  Look at the damages, concerns and worries caused to your car left in the sun:

  • Burns can occur when your skin touches any metal, leather, or plastic items inside or outside the vehicle
  • Your vehicle battery will begin to degrade, leading to months if not years less of battery life
  • Your vehicle’s tires will get Sun damaged, leading to a shorter life of the tires
  • The inside of the vehicle will not be safe to sit in until it is cooled down by outside air or air conditioning, which will slow you down
  • Anything inside the car that is electronic could be ruined or completely lose all battery charging
  • Anything in the car food or drink will melt or be heated up to hot
  • Any plastic water bottles in the vehicle will be heated up to release dangerous chemicals in the plastic into your water

The temperature of your car can reach 65 degrees celsius.  That is hot, and the damage to you paint, your tires, plastic, leather and rubber is what we call a “slow burn.”  Little by little, your car suffers.  Do you see it?  No, you won’t see it right away.

Primer is a paint product that allows finishing paint to adhere much better than if it were used alone.  For this purpose, primer is designed to adhere to surfaces and to form a binding layer that is better prepared to receive the paint. Because primers do not need to be engineered to have durable, finished surfaces, they can instead be engineered to have improved filling and binding properties with the material underneath.

3 Layers of Paint:

There are typically three layers of paint on a car metal surface.  There is primer layer, their is the colour layer and then there is the important clear coat. Car manufacturers know that the sun mounts huge attacks on their car.  Over years, they have learned that a minimum of three layers is key. Each layer has its unique function.

Primer as a step in the coating process of a car body.

In practice, primer is often used when painting many kinds of materials. Priming is mandatory if the material is not water resistant and will be exposed to the elements.  Primers can also be used for dirty surfaces that, for some reason, cannot be cleaned, or before painting light colors over existing dark colors.

Primers can usually be tinted to a close match with the color of the finishing paint. If the finishing paint is a deep color, tinting the primer can reduce the number of layers of finishing paint that are necessary for good uniformity across the painted surface.

There may be a maximum time frame within which a topcoat should be applied over the primer after the primer dries, in order to achieve maximum performance. Depending on the primer, the next coat of paint should be applied as quickly as 24 hours or you may have as long as 2 weeks. Painting after the suggested timeframe may cause performance issues depending on the specific situation. Supposedly, you want to apply the finish coat of paint before the primer fully cures on a molecular level. Doing this allows maximum adhesion/bonding of the topcoat to the primer.

Who Has the Most Durable Paint

Unfortunately, no one can really say for sure. Most every car manufacturer has had problems with their paint quality and durability at some point in their history. From the early clear coats that would peel, or metallic’s that would burn out, to some of the Chevy, Ford, or Chrysler products that would peel after a few years. All the detailing in the world would not have saved any of these problems; this is a case of poor materials, preparation, base coats, clear coats, etc.

Who Has the Thickest Paint?

Once again, this depends. Most every car comes as a two stage paint, which is what clear coat and base coat is all about. You get a thin layer of the color coat, which is followed by a thin layer of clear coat. So even if you were to measure the thickness with a paint gauge meter, how does one know how thick the actual clear coat is vs. the color, or base/primer coats; you wouldn’t. Those using the paint thickness gauges can’t tell you how thick each layer is, so the information is not so useful. It is a nice gimmick, but tells little unless it is “thin.”

Car detailers  will want to know and quickly evaluate is not how thick your car paint is, but how hard is your paint.  The hardness will determine how the detailer will work on your car.  The polishing compounds and the buffer are selected in large part because of the hardness of the paint.  Another critically important issue is the condition of the paint and what problems that need correcting.

Whenproton-saga12V-1 you see cars that are faded, you are actually looking a sun damage. The most obvious car on Malaysian roads are the now pink Proton Sagas (formerly they were red).  UV light will fade a car faster that you can say “Jack Robinson.”  When the clear coat has been damaged with micro cuts and swirls or with over polishing, the clear coat can’t protect the paint from the dangerous UV light.  Here is your car in 5 years if you wax and polish too often!  Better to protect the clear coat with Sierra Glow car coating.  The best in the Malaysian market is Blue Flame by Sierra Glow.
