wet for about 15 minutes, or until
the operator can no longer feel any
surface roughness or even isolated
gritty particles with bare or gloved
finger tips. If this is not done thor-
oughly, rust staining may soon re-
develop. Be sure that the entire acid
cleaning procedure is performed in
a sheltered area so that the work
will be kept as cool as possible to
prevent rapid evaporation of water
and consequent surface drying. Do
not work in the sun.
3. Rinse with clear water. This
must be done very thoroughly to
prevent possible corrosion.
No traces of acid should be left
on any surface. Bright trim parts,
particularly anodized aluminum
and stainless steel, may be stained
by prolonged contact with the
cleaning solution. Painted areas
also can be spotted by prolonged
exposure.
It
is also important to
keep the oxalic acid cleaner solu-
tion from leaking to the inside of
the car because some fabrics might
be bleached or discolored by the
solution.
If the fall-out is not completely
removed or is deeply imbedded in
the paint film, cleaning with the
acid detergent mixture must be
repeated. This may be aided by

using a fine scrub brush, possibly
a nylon bristle type. Make sure
that the light scrubbing required
does not scratch the paint.
It
is
sometimes helpful to briskly rub
the work with a mixture of equal
parts of oxalic acid cleaner and
Ji'oMoCo cleaner wax polish (SA-
19519-A) using a piece of heavy
toweling. Again, a thorough water
rinsing is extremely important.
Sometimes small black spots re-
main after the oxalic cleaning has
removed all iron based fall-out. Such
deposits might be asphaltic or they
might be over-spray. These usually
can be removed by rubbing vigor-
ously with a cloth saturated with a
rnixturc of kerosene and Actusol
( about five parts of kerosene to one
part of Actusol). Any residue of this
-;ulvent mixture may be readily flush-
(d
off with water.
Organic Fall-Out. Organic fall-out
may result from parking cars under

1. Clean· the surface to be painted
with wax and silicone remover.
2. Feather-edge the damaged areas
with No. 400 grit wet or dry sand-
paper. (Prime all the areas of the
bare metal with M-6J-12S Primer.)
3. Mix the paint according to the
instructions on the can and spray
several light coats. Allow the paint
to become tacky between coats.
4. Spray the entire area sparingly
with Lacquer Leveler ( 87 A-645-S)
which will blend the repaired area
with existing painted surfaces.
RATTLE ELIMINATION
Most rattles are caused by loose
bolts or screws. Foreign objects such
as nuts, bolts, or small pieces of body
deadener in the door well, pillars,
and quarter panels are often the
source of rattles. Door wells can be
checked by carefully striking the un-
derside of the door with a rubber
mallet. The impact made by the mal-
let will indicate if loose objects are
in the door well.
In the event that tightening the
bolts and screws, located on such
assemblies as the doors, hood, and
deck lid, does not eliminate the rat-
tles, the trouble is probably caused
by misalignment. If this is the case,
follow the adjustment and alignment
