Rust, like pruny fingers or hermit crabs, is a result of neglect and overexposure to water. Care for your carriage with today's Groupon: for $59, you get a vehicle rustproofing treatment at Sun Tech Auto Services Station (a $169 value).

Sun Tech's auto savvy repairmen freeze time with rust-preventing treatments that keep sparkling paint jobs looking fresh as the day a robot applied them. Deft hands massage an oil-based rust deterrent onto the shining skin of workaday chariots, causing engines to purr and bumpers to nuzzle them with affection. The 30- to 45-minute treatment endures the passage of time and the elements of all seasons with stoic disregard, protecting chassis from rust and allowing them to slip through unwanted hugs for years. Sun Tech's cinderblock shop boasts little in the way of decor, spartanly adhering to a clean workspace featuring only chests with treasure troves of tools inside and the hydraulic muscle of car lifts.
