 As you know, there's an incredible product that protects your car's dash and steering wheel from the sun, keeps your interior cooler, and fits your windshield perfectly. I like things that fit right and work like they should. That's why I love AutoHeatShield. It's a windshield sunshade that keeps your car up to 40 degrees cooler while protecting the interior. Custom fit for your vehicle's windshield. It won't fall down like generic sunshades.
