Long panels reveal waves and uneven repair work that shorter blocks can miss. The full-size Dura-Block AF4419 covers a broader section of the surface with each pass, making it suitable for blocking hoods, roofs, doors, and quarter panels.
Although long enough to bridge surface irregularities, the block remains flexible enough to follow the gradual contours of an automobile. Its hook-and-loop face supports fast abrasive changes and allows usable sheets to be removed and reattached.
