While you can wax the film, be sure the product you are using doesn’t contain Naphtha or Kerosene in concentrations over 5%, and avoid waxes that contain dyes. For best results, we recommend using our XPEL Flawless Finish Paint Protection Film Sealant or XPEL Ceramic Boost. This product has been specially formulated for use with polyurethane paint protection films to provide the maximum protection and gloss, while containing no ingredients that would cause discoloration over time.
