Magnetic Windshield Cover

What's this?

From the website:

Heavy–duty plastic windshield cover holds securely to car with built–in magnets.

Keeps windshield free from snow, frost, bugs, bird droppings, tree sap.

Keeps interior cooler in summer, too!

7–foot x 3–foot cover folds to fit in glove compartment.

$2.99 here.

Although not noted on the website, this device will not work if you own an Audi with an all–aluminum body.

Oh, yeah, one more thing: unless you are a stunt driver for Enterprise Rent–A–Car it would probably be best if you were to remove the cover from your vehicle before its scheduled departure.
