The conformable sander is then placed on the guide
and is moved back and forth to shape the body line. The last
of the filler is sanded from the body line by raising the outer
plastic sheets from one end to the sander. This will allow the
sander to reach slightly deeper into the body line and sand
out the very bottom of the body line. Figure 8-61 shows a
contour sander in use. This particular sander has different
surfaces to match the contours of various body lines.
One common problem when using filler is the
presence of pinholes. Pinholes are air pockets in the
cured filler. Figure 8-62 shows pinholes. Blowing a
stream of compressed air over the cured and sanded
filler can reveal this problem. The air will blow out sanding
dust from the pinholes. Pinholes can be corrected with
an application of putty. To minimize sanding, use a razor
blade to apply the putty. The sharp edge of the razor blade
will fill the pinhole with putty and remove the excess. After
Figure 8-58. A—The air file should span the filler and
be moved up and down. B—Using the edge of the air
file will prevent the file from flattening the crown.
Figure 8-59. Attaching the sandpaper to the curved
side of the block allows the block to be used to sand
filler on a concave surface.

body filler to shape the body line.
