What lens filter can bring out texture in peeling paint under overcast light?

I’ve been trying to capture the texture of peeling paint on an old barn door in overcast light, but my shots keep looking flat and muddy. I’m wondering if a specific type of lens filter would help bring out that subtle, gritty detail without making the image look artificially sharpened.

I actually tried a polarizing filter on a gray day; tilting the camera to catch edge light made the peeling edges pop a little without looking fake or sharpened. It added a touch of separation in the chips and kept the muddy midtones from washing out.

I played with diffusion in front of the lens once; the shadows stayed softer, but the grit started to feel mushy and the texture read less clearly, so I pulled back.

Are you sure the issue is the tool and not the light? Overcast light is flat, maybe you need a different angle or distance so the relief catches the sky or the side shadows.

I dragged the door into a sliver of side light and shot from the corner; the flakes caught a line and looked rougher, but I couldn't tell if it was the lens choice or just luck that day.
