The main function of a sealer in automotive refinishing is to provide a uniform base for the topcoat and prevent bleed-through from existing paints. Sealers create a smooth and consistent surface for the application of the topcoat, ensuring that the top layer adheres properly and performs well. This is particularly important when refinishing vehicles that may have multiple layers of different paint products underneath. By sealing these layers, sealer helps to avoid issues such as color bleeding, where underlying colors can affect the appearance of the new paint. Additionally, it contributes to the durability and longevity of the finish by ensuring that the topcoat bonds effectively to a clean and uniform substrate. Proper use of sealer is crucial for achieving a professional-quality finish in automotive refinishing.
