Why Your Car Paint Fades

Imagine driving your car from the bond when it is as painted as new. Few months down the road, its body starts to lose its initial colour. The most common part that starts to fade is the bonnet for saloon cars such as the Toyota Premio, Mark II or any other. For sport utility vehicles such as the Toyota Prado TX, fading sometimes starts with the roof.

What you however need to understand is that the fading does not segregate any type of car. It cuts across; whether you drive a Mercedes Benz of a Toyota. The fading usually forms a whitish layer or cloud on top of your car body.  

Why your car fades

Musa Kimera a mechanic in Ggaaba attributes car fading to a number of reasons. While some reasons are caused by the natural environment around us, some are quite mechanical in nature.

Kimera says that when excessive heat produced from your car engine protrudes through the car bonnet cover without a thick heat insulator attached beneath, it causes the top part of your car body, particularly the bonnet to start losing its colour.

“The heat generated from the engine is quite stronger than sun heat. When your bonnet fails to absorb and contain the engine heat, the outer layer of the bonnet becomes the primary target top. It starts to change colour. At the end of the day, you will see something like a patch on your car,” Kimera explains.   

Cold environment

In Kampala, some tenants who own cars have no home built garages. As such, it means their cars spend nights in the home compound, if they have space anyway. Some resort to gazetted night parking areas, where cars still spend nights in the cold, thereby exposing them to night dew. When your car is parked outside in the cold on a daily basis, Kimera says the dew that forms on the car body overtime settles and penetrates through the car paint and causes it to fade.

Effect of the sun

Similarly, when you leave your car parked under the sun as you go to office, which is mainly driven by the fact that most work places do not have roofed parking areas, your car paint is exposed to hot ultra-violent sun rays that compromise the paint and subject the car to fading.

Not giving enough time for paint to dry

Ivan Kalyango, a car sprayer at Crown Garage in Kyanja Kisaasi says when the hardener, a car paint component that is mixed in the initial car paint was inadequate and not given ample time to dry thoroughly, it may also cause your car body or paint to start fading. 

Similarly, when your car has just been repainted and it is parked outside in the open at night, without being given time to dry from the garage where it is usually kept under a roof, it causes the car body to develop patches, thus fading. The recommended time you should give your car to dry after it has been sprayed, Kalyango opines is approximately 24 hours or one day.  

The procedure of repainting the entire car body, Kalyango advises should be followed when your car has sustained small scratches or dents by a professional mechanic or car sprayer to spray the scratched part and ensure that the new paint matches or blends well with the old paint.

How to prevent your car paint from fading

Covering your car with a tarpaulin, or car covers that are sold in car accessory shops, Kalyango opines does not only keep away dew when you park your car in the open at night but that they also keep away direct contact of sunrays from affecting your car paint.

“When you get the tarpaulin or car cover off your car in the morning, you will find that the dew settled on top and did not get in contact with the car body to compromise its quality,” Kalyango advises.

Other ways you can protect your car paint from fading is by parking under a shade or a roofed gazetted public area.
