The verdict
Conform to the contour, or flatten it.
Sponges flex into whatever shape they're pressed against — perfect for drywall corners, molding profiles, and anywhere a flat block would skip the low spots. Dura-Blocks do the opposite: six rigid shapes that refuse to follow a contour, so the high spots come down and the panel ends up actually flat. Body work wants the block. Trim work wants the sponge.
Pick 3M if
Drywall, trim, curved or detailed surfaces. You want the paper to follow the shape.
Pick Dura-Block if
Auto body or any panel that needs to read flat. You don't want the paper following anything.
