Chapter
12 Bodywork
and underframe
219
panels It
IS
Important
to
flush these off
In
such
a
way
as to
prevent grit from scratchmg the finish The wheel arches and
underbody
need
washing
In
the
same
way
to remove
any
accumulated mud which will
retam mOisture
and tend
to
encourage
rust Paradoxically enough
the best
time to
clean the
underoody and wheel arches IS In
wet
weather when the mud IS
thoroughly wet
and soft In very
wet
weather the
underbody IS
usually cleaned of large accumulations automatically and this IS
a
good time
for inspection
3 PeriodIcally
It
IS a
good
Idea
to
have the whole of
the
underside
steam
cleaned engme
compartment
mcluded
so
that
a
thorough inspection
can
be earned
out to
see what
minor repairs
and
renovations are
necessary
Steam cleaning
1
available
at
many garages and
IS
necessary for removal of accumulations of
OIly grime which
sometimes
cakes thick
In
certam areas
near
the
engme
gearbox
and
rear
axle If steam
cleaning faCIlities
are not
available there
are one or two
excellent grease solvents
available
whIch
can
be brush
applied
The dirt
can
then be SImply hosed
off
4 After
washing
palntwork
Wipe
It
off With
a
chamOIS leather
to give an
unspotted clear finish A
coat
of clean protective
wax
polish
Will give added
protection a
lInst
chemical pollutants
In
the air If the
palntwork
sheen has dulled
or
oXldlsed
use a
cleaner
polisher
combination to restore
the brilliance of the
shme ThiS requires
a
little
more
effort but
IS
usually caused
because
regular vvashlng
has been
neglected Always
check that
door and ventilator opening
dram holes
and pipeS
are
completely
clean
so
that
vvater can
dram
out
Bright
work should be treated
the
same way as
paint work
Wmdscreens and WindOM
can
be
kept
clear of the smeary film If
a
little methylated
Spirits
IS
added
to
the
water
If
they
are
scratched
a
good
rub With
a
propnetary metal polish WIll often clear thiS Never
use
any form
of
wax or
chromIUm
polish on
the
glass
3 Mamtenance
Intenor
Mats and
carpets
should be brushed
or
vacuum
cleaned
regularly
to
keep
them free of
grot
If
they
are
badly
stained
remove
them for
scrubbmg or
sponging and make qUite
sure
they
are
dry before replacement
Seats and
Intenor trim panels
can
be
kept
clean
by a
Wipe
over
With
a damp
cloth If they do become
stained
which
can
be more apparent on
light
coloured
upholstery use a
light detergent and
a
soft nail brush
to scour
the grime
out
of the gram of the matenal Do
not forget to keep
the
headllnmg
clean
In
the
same
way
as
the upholstery When
uSing
liqUid
cleaners inSide do
not over wet
the surfaces
bemg
cleaned
ExceSSive
damp
could
get
Into
the
seams
and padded
interior causing stainS
offenSive odours
or
even
rot
If the inSide
of the
car
gets
t I et
accldentlally
It
IS
worthwhile
taking
some
trouble
to
dry
It
out
properly particularly where
carpets
are
Involved
Do NOT leave ollar electflc heaters inSide the
car
for
thiS purpose
4 MInor repaIrs
to bodywork
1 A vehicle which does
not
suffer
some
damage to
the
body
vvork from
time to time
IS
the exception rather than the rule
Even
presuming
the
gatepost
IS never scraped or
the doors
opened against
a
wall
or
high kerb there
s
always thelikelihood
of
gravel
or
grit being
thrown up and
chiPPing
the surface parti
cularly
at
the lovver edges of the doors and wmgs
2 If the damage
IS
merely
a
pamt scrape which has
not
reached
the bare metal
delay
IS
not
cntlcal but where bare metal
IS
exposed
action must
be taken Immediately before
rust sets
In

owner
will
normally keep
the
follOWing
first aid

can give a

not

suffICIent
toller
to

area
rub down WIth paper and
apply the
matchmg pamt
5
Where the bodywork
IS
scratched down
to
the metal but
not
dented
clean the metal surface
thoroughly
and
apply
a
SUItable
metal primer first Fill up the
scratch
as
necessary With filler and
rub down WIth
wet
and
dry
paper
Apply the matchlOg colour
paint
6 If
more
than one coat
of colour
IS
required rub down each
coat
WIth cuttlOg paste
before
applymg
the
next
7 If the
bodywork
s
dented first beat
out
the dent
as near as
pOSSible
to
conform With the
onglOsl contour
AVOId uSing steel
hammers
use
hardwood mallets
or
Similar and always support
the back of the
panel belOg
beaten WIth
a
hardwood
or
metal
dolly
In
areas
INhere
severe
creasing and buckling has occurred
It
Will be
Virtually ImpoSSible
to
reform the metal
to
the
anginal
shape
In such
cases a
deciSion should be made whether
or not to
cut out
the damaged
piece or
attempt
to
re contour
over It
With
filler
paste
I
n
large
areas
where the
metal panel
IS
seriously
damaged
or
rusted the repair
IS
to
be considered major and
It IS
often bener to
replace
a
panel
or
Sill
section
With
the
appr
pnate
part supplied
as
a
spare
When usmg filler
paste
In
larglsh
QuantitieS
make
sure
the directions
are carefully follovwd
It
IS
false economy to
try and rush the Job
as
the
correct
hardening
time must
be allowed between
stages
or
before
flOlShlOg
W th
thick applications the fIller usually has
to
be applied 10 layers
allOWing time
for each
layer to
harden
Sometimes the onglOal
pelOt colour Will have faded and
It
WIll be dIffIcult
to
obtaIn
an
exact
colour match I
n
such cases It
IS a
good scheme
to
select
a
complete panel such
as a
door
or
boot lid and spray the
whole
panel
Differences Will be less apparent where there
are
ObviOUS
diVISions between the onglnal and resprayed
areas

MaJor
repaIrs
to
bodywork
When
serious
damage has occurred or large
areas
need
renewal due
to
neglect It means certainly
that
complete
new
sections or
panels Will need l l eidlng 10 and thiS
IS
best left
to
the
profeSSIonals
If the
damage IS
due
to Impact
It
WIll also be
necessary
to
completely check the ahgnment
of the bodyshell
structure
Due
to
the principle of construction
of
the
510
models the
strength
and
shape
of the whole
can
be affected by
damage
to
a part
I
n
such
cases
the
services
of
a
Datsun garage
With
speC1al1st equipment
are
essential
If
a body IS
left
mls al l g ned
It
IS
fIrst
of all dangerous as
the
vehicle WIll
not handle properly
and
secondly
uneven stresses
will be
Imposed
on
the
steermg
suspension
engme and
trans
miSSion causmg
abnormal Near or complete
failure Tyre
wear
Will also be
excessive
With the 521
models
where
a separate
chassIS and body
are
used repair
IS
made
easier
In the
case
of major
aCCident
repair If
the ChaSSIS IS
satisfactory
but the
body
requires
renewal thiS IS a
Job
that
can
be tackled by
the enthUSIast but be
prepared to
spend
some time domg It
The front wmgs on
models covered by

are
