HOW DOES A CAR PAINT FADE?
Cars are expensive, and so is their maintenance. Some parts of the car can be easy and cheap to maintain or replace, but that is not the case with paint. Once the car paint fades, the only option is to get it repainted if there is no protection like the paint protection film, wax, or coating and repainting is much more expensive than protecting one’s car paint. Here are a few reasons why car paint fade:
One of the most common misconceptions about paint oxidation is that it is caused by direct sunlight. That is not entirely correct. While the combination of temperature and oxygen causes oxidation, the ‘heat’ is UV radiation. As UV light strikes the clear coat repeatedly, it progressively breaches the coating and begins to melt the paint. It exposes the undercoat of paint to oxygen, and when the metal absorbs heat, fading happens.
People who live near the beach or in cold weather areas are aware of salt’s harmful effect on their gear. Salt stinks, whether it’s creating corrosion on the undercarriage, engine mounts, exhaust pipes, or body panels.
Here’s the kicker: salt is NaCl, or sodium chloride, neither an acid nor a base. It is, nevertheless, quite caustic. The actual problem arises when salt is left on a surface, particularly when it is revealed to UV radiation. Those bothersome salt crystals will progressively eat away at the transparent layer, and gradually the paint surface, as it warms. It soon gets into the exposed metal and causes rust to form quickly.
Some automobile cleaners are effective, while others are harmful to the paint. Any cleaning containing abrasive ingredients is usually a no-go for car lovers. Abrasives, in essence, operate like sandpaper on your car’s paint surface. If you’re using a washrag (even microfiber), it digs into the paint, exposing the under-layer of paint to UV radiation and oxygen, resulting in oxidation. Sending your automobile to the neighborhood car wash is also ineffective.
So, let’s take a look inside a typical combustion engine for a moment. It’s a fact that even the best engines do not burn 100% of the gasoline put into the combustion chamber? It worsens with diesel and other refined fuels containing long-chain carbon molecules.
The rest of the unburned gasoline is discharged as ‘pollution’ from your exhaust system. Other sources, such as coal combustion, create excessive levels of carbon particles, which wind up on your outside paint.
Carbon is made up of tiny molecules that are extremely hard and jagged. Scarring develops as a result of this.
- The paint protection film is like an upgraded transparent vinyl cover. It’s a really thin urethane polymer that protects covered objects from the same stuff that generates oxidation. PPF can last three to 5 years, while some professional-grade products can last more than five years or even decades. Temperatures in Sydney go up to 30 degrees Celcius in Summers with a humidity percentage of more than 70, which is more than enough to fade the paint of your car, so it is a wise option to opt for paint protection film in Australia and especially in regions where it is hot in summer-like Sydney.
- A ceramic coating, also known as nanocoating, is a carefully designed combination of Quartz and other synthetic polymers that attach to the surface area of transparent coatings, plastic, vinyl, bare metal, and even glass.
When it fixes (usually requires just several minutes at first but few more days to completely cure), it hardens swiftly to prevent UV rays, chemicals, salt, and contaminants from entering the surface. It substantially lowers the possibility of oxidation and, as a result, paint fading.
