A sanding sponge is usually better for curved surfaces than regular sandpaper because its flexible foam backing can conform to contours, edges, and uneven shapes more easily. This helps distribute pressure more evenly and reduces the risk of deep sanding marks.
For automotive surface repair, sanding sponges are especially useful on curved car panels, bumpers, body lines, primer surfaces, and small repair areas. They are suitable for both fine sanding and surface preparation before painting or polishing.
For best results, choose the right grit for your application and avoid pressing too hard. Let the abrasive surface do the work while keeping steady, even movement across the curved area.
