In fact, many car insurance companies even advertise their best car covers as water-free. That their covering fabric will completely dry the water at the entrance to the inaccessible outer fabric of the fabric. In fact, this is the exact opposite of what the cover is made of. The car cover is designed to protect the consumer’s car from external influences. Having a “100%” waterproof cover can do the opposite. What the consumer should look at and ask is that if the cover they are buying is a “one-way barrier” to help keep moisture out, but it can remove the trapped moisture. ”
