Sanding block velcro, soft 70 x 400mm.

Flexible Velcro Sanding Board (70 mm x 400 mm) is a professional body shop sanding file board engineered for accurate leveling and contour sanding of curved automotive panels. Featuring a flexible, adjustable backing construction, this block easily conforms to both convex and concave surfaces, matching the natural body lines of the vehicle. The Hook & Loop (Velcro) system holds abrasive strips securely in place and allows effortless sheet changes during prep operations.

Its 400 mm working length makes it an essential tool for eliminating high/low spots, ridges, and waves when sanding polyester body fillers, spray putties, and primers over doors, hoods, fenders, and roofs.
