It is best to use PEVA material on the outside of the car cover.
It is a mixture of PE and EVA materials. It has high durability, waterproof, dustproof and heat preservation functions, and has a very good reputation in the industry. As for the inside of the car jacket, smooth nylon cloth material is used, which has good wear resistance.
Main advantages:
Do not choose some poor-quality car covers, not only will it wear badly with the car paint, but also the dustproof and waterproof functions of the car may not be so good due to sewing defects, and jerry-built materials may also occur. There is no flame retardant added at all. If it is exposed to the sun for a long time or encounters fireworks and firecrackers, it is easy to be dangerous.
