Water Spots

Water spots on a car’s paint are caused by hard water deposits left behind after washing the car. Hard water contains minerals, such as calcium and magnesium, which can leave behind spots on the p[aint when water evaporates. Such spots are more likely to occur when the car is not rinsed thoroughly after washing.

How to Fix?

For minor water spots, you can use a mild acid, such as white vinegar or a lemon juice and water solution, to remove the spots. However, if needed, stubborn spots can be repaired using aggressive cleaners or a clear coat.

Fading

Car paint can fade due to different reasons. The most prominent factor contributing to fading is damage from the sun. The sun’s UV rays cause the paint to fade over time, especially if the car is frequently exposed to direct sunlight. Using poor-quality paint can also contribute to fading over time.

How to Fix?

If the fade is minor, you may apply touch-up paint to the faded area to restore its color and shine. However, if the fade is extensive and affects a large portion of the car, it must be repainted.

Damage from Sun

Persistent sun exposure can cause various problems for a car’s paint, including fading, discoloration, and deterioration.

The heat from the sun can also cause the paint to dry out and become brittle, which can lead to cracking and peeling.

How to Fix?

In case of minor damage from the sun, you can apply touch-up paint or wax the affected area to restore shine. For severe damage, you may need to get the car repainted.
