JE Adams Tire Shine unit is designed to be used after the vehicle has been cleaned. It is used in place of Armor All to give tires a glossy finished look by covering the tire with a light mist. An on/off button on the gun controls overflow and you won't have to worry about towels, rags, or messy pads left behind as no wiping is required. With an average vend time of $1.00 for 1 minute this is sure to be a profit center for you.
