Two-tone Paint Masking: Balancing Perfection and Speed

More and more customers demand customized vehicles, including two-tone car paint. Undermask and you spend time removing paint, overmask and you have to go back and repaint spots. To keep costs down you need to get it right quickly and efficiently. You also need to understand your process and decide whether to paint the entire body first or just one half. 3M can help by collaborating with you to find solutions that save time and money.

A folded masking film is pre-taped on one edge, then unfolded, and all edges must be taped down to prevent flapping in the wind of the bake over. These films are specially engineered to withstand the heat of paint curing ovens without melting or ghosting the underlying clearcoat, and masking and fine line tapes are designed for clean one-piece removal after exposure to a bake cycle.

    Paint Body and Bake

    Painting the entire body one color first has the advantage of making the roof paint slightly thicker so water will flow away rather than pool at a paint ridge. The speed required on the production line may mean that after baking further masking is done while the vehicle is still warm.

    Mask Front and Windshield

    Apply pre-taped masking film 3M™ High Temperature Paint Masking Film 7300 and open it out, making sure to secure the film with 3M™ Performance Masking Tape 2380. Custom applicators are often used, and this is also the time to mask a sunroof.

    Mask Back Hatch

    Rear hatches have more complex shapes and even a custom applicator may not work well, while applying by hand is hard to do consistently. Die-cuts of Scotch™ High Temperature Fine Line Tape 4737 can be made to match these complex shapes, with tabs to make placement consistent and easy.
