Expose high and low areas across large repairs with the extended sanding surface of the Dura-Block AF4403. This full-size block is designed for leveling filler and primer on broad, flat, or gradually curved automotive panels.
Flexible EVA rubber helps the block follow the general panel shape without conforming too closely to every surface defect. The PSA face accepts sticky-back abrasive sheets or roll material for a secure attachment during long blocking strokes.
