No 4 layers. Just 1 thin layer of plastic. Living in a hot climate, I worry about melting my car. I am sending it back because I would rather risk leaving the machine open to the environment than use it. I hope to find something thicker and better. I've included a picture of the edge of the material so you can see how flimsy the plastic is.
