a. Wash the interior of framerail structures through
drilled access holes to remove mud, dirt, and rust. Use
of a high pressure washer will facilitate this operation.
Observe the water flushed through the rails to deter-
mine when it is clean.
b. Allow at least four hours for vehicle drying.
Additional drying time may be required if unfavorable
weather conditions exist. Compressed air may be used
to speed up the drying process.
c. Prime and paint those areas showing bare metal,
Allow painted areas time to dry before rustproofing.
