We are a national high-tech enterprise. At present, there are many kinds of self-woven and cooperatively processed fabrics, including microfiber warp-knitted towel cloth, weft-knitted towel cloth, coral fleece, etc.
Acid rain, which has become more common, is another matter. The harsh chemicals in acid rain can gradually damage the paint and finishes of unprotected vehicles. If you park your vehicle outdoors in an urban or industrial setting, you will need a Car Cover Fabric to protect your vehicle from acid rain.
You may have seen some car covers that are advertised as "waterproof". In theory, these coverings are designed to completely block rain and moisture from reaching the car below. These covers are usually made of plastic film or plastic-coated fabric—a material similar to the plastic tablecloths you can buy at the dollar store. The idea behind this design is that if the object is dry before putting the lid on, it should stay dry and prevent condensation from forming. The logic is simple, but there are serious problems with these so-called "waterproof" enclosures.
Covers that claim to be 100% waterproof keep moisture out — which is exactly what we want — but, at the same time, they keep moisture from escaping. Since waterproof covers are generally cheap to manufacture, it is possible (read "unavoidable") that some condensation will form under the cover and get trapped. This can lead to water spots on the vehicle's surface or more expensive damage, such as oxidative rust. What's more, trapped moisture can cause mold and mildew to form inside the vehicle, which is a non-negligible health hazard in addition to the "nausea" factor.
With that in mind, do waterproof car covers exist? We may not be the official myth busters, but we can say it with confidence: waterproof car covers are a myth. Plus, they're a myth that tempts many well-meaning buyers to spend too much on a cheap and ineffective car cover -- ultimately damaging what it's supposed to protect.
The waterproof car cover provides the best protection against water. Like sportswear, car covers should be able to breathe. As "waterproof", your cover will block most of the rain. However, when some water does seep in (which is unavoidable in the event of a downpour), it will be able to evaporate through the layers. Therefore, an important requirement will be met - your vehicle dries quickly when wet!
With a waterproof cover made of specific materials like super weave or Noah, you can put the cover directly on a wet car and expect it to dry within hours. When buying a cover, pay attention to whether the cover is suitable for indoor/light use, not outdoor use. Indoor/light use has limited water protection, while outdoor use can withstand harsh weather conditions such as rain, snow, and hail.
What about acid rain? A waterproof cover is the best option for preventing acid rain. It is the chemical deposits that cause acid rain damage, not the water itself. This chemical deposit can get stuck in the hood, preventing it from corroding the car's finish.
