Which action is taken to level nicks and scratches after cleaning?

The appropriate action to level nicks and scratches after cleaning is hand sanding. This technique involves using sandpaper to smooth out surfaces, allowing for the removal of imperfections such as nicks and scratches. Hand sanding is particularly effective because it provides better control and precision, enabling the technician to ensure that the surrounding area remains intact and that the surface is even.

By hand sanding, the technician can progressively smooth the area, preparing it for any subsequent finishing work, like painting or priming. This method is crucial to achieving a flawless appearance in the final product, as it ensures that any uneven surfaces are addressed adequately.

While applying a filler is an essential step in repairing deeper scratches or nicks, it would not be the first action taken to level those imperfections after cleaning. Automated sanders can also be used, but they might not provide the same level of control needed for smaller, detailed areas as hand sanding does. Washing the area again is generally redundant at this stage, as the surface should already be clean before any sanding takes place.
