Repairing brush marks in a painted surface effectively requires attention to surface preparation and technique. Lightly sanding the affected area smooths out any imperfections left by the brush marks, creating a more uniform surface for repainting. This step is crucial because it promotes better adhesion of the new paint as well.

After sanding, repainted areas should be applied using a smooth technique, which includes using the right type of brush and ensuring that paint is applied evenly and without excess. This approach not only helps to conceal the previous brush marks but also contributes to a professional-looking finish that blends seamlessly with the surrounding areas.

The other methods would not provide the same level of refinement or quality in the repair. For instance, reapplying paint without sanding can often lead to a similar issue if the surface has not been adequately prepared, while using a thicker brush may result in further visible marks rather than eliminating them. Applying a clear coat might enhance shine or protection but won't eliminate the underlying brush marks themselves. Therefore, the most effective repair method focuses on correcting the surface with proper sanding and careful repainting.
