Cars are a big investment, which is why they must be protected with smaller investments such as garages or tarps made from liberal-arts degrees. Protect your investment from the elements with today's Groupon: for $99, you get 12 inches of 3M clear bra hood-and-fender treatment at Tint Crafters of Centennial Inc. (up to a $200 value).

The licensed and insured technicians at Tint Crafters of Centennial Inc. deftly apply 3M clear bra treatments to protect cars’ pristine painted surfaces. The durable clear coating repels debris, keeping stone chips, gravel, or pithy bumper-sticker slogans from scratching the finish. Clear bra treatments on the hood and fender vary by size ($199+ for 12 inches), and techs can affix the damage-defying treatment to headlights ($50/lens), fog lights ($20/lens), and side mirrors ($20 each) as well. This Groupon is valid for a 12-inch treatment, measured from the lowest point on your car's hood. 3M has a five-year warranty on all materials, and all services from Tint Crafters are backed by a lifetime warranty.
