This is the Protoform Better Edge System Sanding Block. PROTOform introduced the Better Edge: Sanding Drum to help create the perfect wheel well. Now, PROTOform has developed a product to help create the perfect straight edge as well as all the nooks and crannies of your R/C race body, the Better Edge: Sanding Block.

The Better Edge: Sanding Block is another tool for the racer who takes pride in finishing off their concourse-worthy race body. The tool is formed from injection molded nylon with a shape that is both ergonomic and racy. Use the straight edge to smooth out scissor imperfections along the bottom edges or rear wing of your body, then rotate the block to finish off tightly curved edges such as the rear of your 1:12 or 1:8 on-road bodies, off-road body wheel wells or suspension cutouts. The rounded ends of the block are two different radius sizes for different applications, ¼” and ½”. It can also be used to sand parts and tires.

Each block includes a form-fitted strip of high-grade, 120-grit sand paper fastened to the block with a low-profile hook-and-loop system. A spare strip is also included, and replacement strips are available in 2-packs (PRM6108-01).

Protoform Better Edge: Sanding Block
Good product smooths bodies nice and allows corrections if you don't cut perfectly straight.

Protoform Better Edge: Sanding Block
Excellent product. A must if you prepare quite a few bodies each season. Leaves a perfect edge that is less prone to cracking.
