For most car owners, especially those without a home or portable garage, a car cover is a convenient accessory. It maintains your car in pristine condition for a long time by keeping off weather, UV rays, and water.

With almost all car covers able to keep off the water, many people wonder whether all of them are waterproof. Well, not all covers are waterproof, but almost all car covers are water-resistant.

Are Car Covers Waterproof?

Not all car covers are waterproof. There are three basic types of car covers: waterproof car covers, water repellent covers, and non-water-resistant ones.

Water-resistant car covers are manufactured with fabric that is coated with plastic films. They will ensure no water penetrates the surface of your vehicle. On the other hand, this cover will not allow any moisture and condensation formed on your car to escape.

Water repellent covers block entry of water into the surface of your vehicle, but they will not block 100% of it. As much as very little water can go through them, they also allow condensed water and moisture in your vehicle to escape.

Non-water-resistant ones will allow water to go through them onto and out of the vehicle. But they will allow free air circulation keeping your car aerated and protected from other weather elements like UV light
