Epoxy Surfboard Ding Repair Step 4 "Shaping EPS Foam"

Step 4: "Shaping EPS Foam". Use a block sander and 100 grit sandpaper to shape the EPS foam plug to the contours of the board. It sands really easy so don't go too fast or apply to much pressure or it will cause the foam to tear apart. I started with the rail and sanded it down flush.
