Car owners can indeed get paid to put ads on their cars—a procedure known as “wrapping”—but some solicitations to join such advertising companies are scams.

It was a fake. “Monster has no car-wrap program,” said Tamara Taylor, a spokeswoman for the Corona-based company. “This is something that's been going on for a while,” she said, adding that Monster Energy is cooperating with authorities investigating the racket.

The Mountain Dew Decal Scam is what is known as a 'car wrap scam'. They want you to pay for the installation of a decal on your car. In exchange, they will give you money for advertising for them. This has been seen over and over in other similar scams, like the Bud Light Scam.

3D Changer is a car configurator that helps wrap shops and designers visualize customized cars in 3D. Select a car model, choose a wrap film or upload a design and see changes via real-time 3D visualization.
