Paint Polish and Wax Available here. You want your car to shine as you cruise down the road, which is why you regularly treat it with paint polish and wax. Sure, you could just apply a layer of wax to your car and be done with it, but you know that to get a real shine you have to first treat the exterior with paint polish. The polish smoothes out the upper most layers of paint, which causes your car to shine when the sun hits it. When you add wax over the newly polished paint, you are sealing in the polish and the shine. By performing regular paint polish and wax treatments on your car, you can keep it shining all year round.
