a. Wash interior of framerail structures through
drilled access holes to remove mud, dirt, and rust. Use
of a high pressure washer will facilitate this process.
Observe the water flushed through the rails to
determine when the structure is clean.
When cleaning items, water may be dis-
charged in excess of 1200 psi (8274 kPa)
b. Allow at least four hours for vehicle drying.

Additional drying time may be required if unfavorable

to speed up the drying process.
c. Paint and prime those areas showing bare metal.
Allow painted areas time to dry before rustproofing.
Steam cleaning will not be used.
Section Ill. RUSTPROOFING PROCEDURES
There are areas where a 10 mil wet film
thickness cannot be obtained without
wasting a large amount of compound. In
those areas, complete coverage of the
surface area is necessary at whatever
