While you can apply wax to the film, make sure the product doesn’t contain more than 5% Naphtha or Kerosene, and avoid waxes with added dyes. For optimal results, we recommend using XPEL Flawless Finish Paint Protection Film Sealant or XPEL Ceramic Boost. These products are specifically designed for polyurethane paint protection films, offering enhanced gloss and long-lasting protection without the risk of discoloration.
