CARGO BED COVER (CBC), TYPE IV, 5 T CARGO TRUCK, MTV, AND MTV TRAILER
Place patch (1) over prepared area in same orientation used in earlier step.
Align holes (2,4) and, using hand blind riveter, install 1/8 inch (3.18 mm) diameter blind rivets in
Cure adhesive at room temperature (75 degrees F) for 72 hours. If a heat source is available, alternate
cures can be achieved by exposing the repaired area to 150 degrees F for 3 to 4 hours, or 200 degrees F
for 40 to 60 minutes. If 150 degree F or 200 degree F cures are used, allow additional time for repaired
area to warm to curing temperature. Ensure that the surface temperature of the CBC does not exceed
225 degrees F.
Clean repaired surface. Caulk around patch in accordance with WP 0025.
Apply alodine solution. Apply the alodine solution with a brush, paint spray gun, cellulose sponge, etc.,
to the cleaned and rinsed aluminum surface, liberally, quickly and evenly. Allow it to act from 1 to 5
minutes before rinsing.
The solution should be applied to only as much surface as can be coated and rinsed before the
alodine solution dries.
Proceed with the coating and rinsing until the entire surface is coated with alodine.
Rinse. Before the alodine solution dries, wipe it from the surface with a clean cloth or sponge wet with
clean water. The alodine solution may also be rinsed from the surface with clean water from a hose.
Dry. After the rinsing has been finished, allow the work to air dry. Drying can be speeded by wiping with
clean, dry rags. Clean, dry, compressed air should be used to blow moisture from joints, depressions,
etc., and to speed the drying. When the surface is entirely dry, the part is ready for service without further
treatment, or if desired, it may be painted in accordance with manufacturer's directions.
