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.
17-3. Cleaning Procedures.
When cleaning, water may be discharged in
excess of 1200 psi (8274 kPa) from high
pressure water equipment. Serious injury
could result. Eye protection must be worn
to prevent injury.
Steam cleaning will not be used.
Section Ill. RUSTPROOFING PROCEDURES
17-4. 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
Do not spray any portion of moving compo-
thickness is obtainable.
nents, transmission, transfer case, cylin-
ders, pumps, valves, prop shaft, exhaust
For rustproofing procedures of specific
system, rubber bump stops, brakedrums,
tractor items, refer to Figure 17-4
brake backing plates, parking brake linkage,
shift linkage, tires, electrical components,
engine linkages, or air intake systems. Cov-
a. Dry Film Thickness Requirements. A five mil dry
film thickness is required for adequate rustproofing pro-
er all areas with paper where necessary.
