PERFECT MASKING, and an evolution of our FOAM MASKING cord, now with flat, semi-rigid foam in a diagonal shape, and another softer foam glued to its base, gives it an L shape instead of the old T shape. new PERFECT MASKING cord is placed quickly and easily on the edge of the different widths of the door thicknesses, preventing paint from entering the interior and leaving the perfect and imperceptible disguise in sight. The cord does not take off with the heat of the cabin or leave residues on the plate, it has a silicone paper protection on the adhesive to protect it from dust, thus preventing it from becoming sticky at the time of application.
