Haha, nah, you have to stick a circular magnetized disc to the glass roof. Then, you install the mesh sunshade. Then, you place a magnet on top of the sunshade that adheres to the disc. It works well and prevents the sunshade from sagging. It’s not a necessity but the sunshade will without question sag, like 4 to 5 inches from the glass, without something there.The glass is magnetic?
