Keep your vehicle cool this summer while it's parked by adding this Retractable Automatic Windshield Sunshade. Simply stick the rubber window surface suckers on the windshield from the inside, then attach and slide the retractable car window cover to lock it in for a perfect fit. The best part about this universal car window sunshade is that it can be cut down to the correct size. If it is too long just take a pair of scissors and remove the unneeded ends as this is 100% modifiable if needed. Want to see how it works? Check out the video below !
