Select an aluminum skin patch that overlaps the puncture or cut by one inch in
all directions.
Position the aluminum skin patch over the puncture and lightly scribe the area
of the patch on the shelter skin.
Remove all paint or foreign matter from the puncture area and an area approxi-
mately one inch around the scribed mark using an emery cloth and toluene
solvent.
With the aluminum patch over the puncture area, drill holes for 3/16 inch pop
rivets (#11 drill) around the perimeter of the patch, 1/2 inch from the edge of
the patch and on one inch centers.
Roughen the skin surface with coarse grit emery cloth. Be sure that the area
is completely clean. Do not touch the area with the hands or wipe with an oily
cloth.
Fill the puncture with a fiber filled polyester resin. Then, smooth out evenly as
shown in Figure 4-4, B.
Allow the resin to set thoroughly. Then, sand off excess flush
of the skin surface.
Use the aluminum skin patch as a template to mark pop rivet
of the shelter, and drill #30 holes in the skin of the shelter.
