We put in a lot of effort into the details to ensure you, the customer, have a quality wheel. One of the thing we pay close attention to is not allowing paint in the lug pocket area. We never allow any paint in the lug pocket where your lug nuts fastens. This ensures your lug nuts stay put where they should be after torquing them down. If there were a layer of paint between the wheel and the lug nut, paint could break and loosen the lug nuts.
This could potentially cause the lug nut to loosen, and therefore the wheels falls off the vehicle.
