That is my understanding. Hopefully no paint correction needed.
However, the Xpel website says: Before every installation, our skilled installers will clean and prep the finish of your car. Depending on the condition of the paint, this can include steps such as claying the surface to remove impurities, repairing rock chips, color sanding trouble areas and buffing to a high gloss finish.
Our expert installers will also remove emblems, marker lamps, mouldings and other trim as needed to allow the clear bra's edges to be hiden where possible, providing the most invisible protection possible.
