We remove iron, tar, and contaminants for the ultimate smooth finish. Then, we enhance the shine with a gloss polish and lock it in with an ultra-durable 12-month ceramic coating. This advanced technology provides incredible gloss, superior protection against the elements, and makes future cleaning a breeze! Your windshield gets polished to remove built up grime and also gets a 6-month coating for crystal-clear visibility. Wheels and glass are included too!
