Similarly, covering a car with a wet car cover brings about the same side effect as the first instance where the wet car is covered with a cover.

Why you should not put the cover on when the car is wet

Car covers play the essential role of keeping the car’s paint and interior protected from the direct effect of the harsh sun’s rays.

Continuous exposure to the sun can cause fading of the car’s paint and in severe cases cause it to develop cracks. Also, the sun dries up the car’s interior and causes cracks in the car’s dashboard, seats, and other aspects of the car’s interior. It is for these reasons that car covers are considered relevant for all car owners.

Even when the car is parked in the garage or under a canopy or carport or umbrella, car covers are still relevant in this situation to protect the car from dust, dirt, and minor scratches.

When a car is wet, it is not encouraged to cover it up with a car cover, this is because the cover may trap water and stop the water from ever drying up.

The car cover is designed in such a way that the outer aspect of the cover is usually waterproof, which is impervious to water. Therefore, when a car is covered up, it does not get wet even while standing in the rain.

The inner aspect of the cover is however not waterproof, this aspect is designed to absorb water. When a wet car is covered up with a car cover, the outer waterproof aspect of the cover traps the water, cuts it off from air, and prevents the evaporation of such water.

The trapped water becomes a culture ground for the growth of moulds which can affect the car’s finish and reduce its resale value.

The protection offered by car covers is not absolute, when the car is parked outside for a long-time duration, continuous exposure to rain or snow may cause the development of molds as well. this comes on as a result of the activity of anaerobic bacteria.

Aside from molds, your car’s paint may also suffer from scratches when the car is covered while wet. This will be the car when the wetness is from dirty water that contains debris and dirt.

When you drive through rain, the car is usually covered up with dirt as you run through mud or water collection on the road.

Covering such a car up immediately as you arrive home with a car cover will cause the paint to get scratched when the cover is been pulled off.

One other adverse effect of covering a car up while it is still wet is the appearance of water sports on the car. Irrespective of the type of water that caused the wetness, be it rain or distilled water when a wet car is not allowed to dry up before being covered with a car cover, this could lead to the formation of wet spots on the car’s paint. While this may not be a major consequence, it affects the looks of the car.

More serious consequences of this action are rusting some of the metallic components of the car’s exterior. When a wet car is covered up with a car cover, the trapped water may react with whatever amount of air is available and lead to rusting of exposed metallic components of the car.

If the car’s paint already has cracks, the water may penetrate these cracks and cause rusting of the underlying metal.

When a car cover is drawn over a wet car, after some time, the inner aspect of the cover may become stuck with the car and prove difficult to remove.
