Will treating my car cover with Scotchguard or another compound make it more water resistant?
In almost every instance, our outdoor car cover fabric has been crafted with some sort of DWR (durable water repellency) treatment during its manufacturing process. The effectiveness of such a treatment will also depend on the construction of the car cover fabric. If you can hold the fabric up to light and see small open areas between the yarns, no treatment will increase the fabric’s water resistance. In most cases, adding additional treatments won’t increase your car cover’s protection, and aren’t worth the cost.
