Sanding Recessed Panel Doors with Sponges

What happens here

When sanding a recessed panel door (like a shaker style), a flexible foam sponge (e.g., 1/2 inch or 10mm) is used on the orbital sander. The flexibility of the sponge allows it to contour to the edges of the recessed panel and the surrounding rails and stiles, ensuring uniform sanding without damaging the detailed profiles. This technique is demonstrated by lightly pressing the sander onto the surface, allowing the sponge to flex and reach all areas. The sponge is particularly effective for these complex shapes, which would be difficult or impossible to sand efficiently with a rigid flat pad.
