Hook marks, also known as shielding or the robbing effect, can be hard to avoid. As parts are put on hangers to be coated, a portion of the hanger can be located in between the coating equipment and the part. This space leads to bare spots (hook marks) or lightly covered areas. Inside corners, drawer handle indents on filing cabinets, and other recessed areas pose another challenge to coating. The more narrow and deep the recessed area is, the harder it is to coat. Manually applied touch-up paint, matched to the exact color of the product, can cover these marks and recessed areas. Touch-up paint also can be used to cover nicks, chips and imperfections caused by installation or assembly.
Touch-up paint can be applied in one of three ways: aerosol, brush-in-cap bottles or paint pens. Each type has an appropriate application situation. Aerosols are good for larger blemishes and recessed areas, while brush-in-cap bottles and paint pens are ideal for small nicks or scratches. Before purchasing touch-up paint, carefully review the area to be covered and then decide on which application method you need.
