Review on Big Ant Windshield Snow Cover with Magnetic Elastic Hooks, Four-Wheel Fixing & ❄️ Reflective Warning Bar, All-Weather Protection - Ice, Sun, Frost, and Wind Proof, Fits Most Vehicles by Hassan Tomlinson

I use this on a 1996 Chev Lumina. It's big enough, easy to install and remove. So far I've only used it in summer, but it should work against frost, ice or SNOW. Attached magnets and rubber bands with hooks secure the sign well to the car. It would fit in an even bigger car than mine, but a smaller car might not fit the side mirror pockets. I recommend this product.
