Now you can sand precise auto body contours fast and easy. The Malco 5" Conformable Sander (CSH5) is the first re-usable sanding block that holds a hand-pressed contour throughout the entire sanding operation. A unique segmented block design quickly conforms to curved geometry down to an 8-1/2" (216mm) inside block radius, to produce convex, concave or S-curve contours. An internal aluminum memory bar holds the desired contour shape in place for sanding and the segmented block can be set and re-set with reasonable hand force. The ability to easily grasp the generous contours of the sanding block itself reduces fatigue and ensures even-pressure sanding. The conformable sander uses standard 2-3/4" (70mm) wide hook and loop backed abrasive paper. A thin, ultra-flexible, paper-slide interface allows the block contour to be changed without buckling or tearing the paper. There is no need to reposition the paper, change the block contour or remove the slide when changing out the paper grit or replacing worn paper. The slide accepts standard paper tear-off increments. Both the engineered polymer block and slide are impervious to shop solvents and will not mar or scratch the auto body surface. Inexpensive paper-slides are a replaceable part and available in handy 3-packs.
