I recently bought this cover because it's waterproof and not even close even when it's humid outside, it goes straight through the car and when it rains less work to Remove because all the particles on the inside of the coating are now covering your car. I called the owner and he 100% agreed. Of course he said he would put me on the list because they should have a really waterproof one next year. And that's not going to happen. good internal coverage, although not external.
