FINISH
CARE
Urethane
paint
is
the
standard
exterior surface
finish
on
the
Baron.
Special
procedures
such
as
cleaning,
removal,
application
and touch
up
repair
are
listed
to
aid in
preserving
and
maintaining
the exterior
finish
of
the
airplane.
Each
type
of
paint
available
for
the
Baron
is listed
by
paint
name
and
part
number to
aid
in
reordering
matching
colors.
Airplane
areas
which
require
other
paints
and
special procedures,
such
as
battery
box and
lid,
magnesium
surfaces,
etc.,
are
also listed.
NOTE:
Ascertain that
all
placards
are
in
place
and
legible
whenever the
airplane
has
been
repainted
or
touched
up
after

Replace
any
placards
that have been
inadvertently
defaced
or
removed.
ENVIRONMENTAL
FALLOUT
(ACID
RAIN)
After
the
specific
curing period
of
new
paint,
avoid
outside
storage
when
conditions
exist
where
moisture
may
collect
on
painted
surfaces.
Acids
which
remain in
standing
water
can
stain
the
paint
topcoat
and
cause
permanent
damage
to
the
finish. Flush
off residual
moisture
with
clean
tap
water
and
dry
the
surface.
At this
time,
waxing
the
surface
can
provide
protection
from acid rain
damage.
Any
standing
moisture
from
atmospheric
sources or
moisture
residue
should
be flushed
off
with
clean
tap
water
as
soon
as
possible
and
dried. The
surface
may
be
kept
well waxed
as
a means
of
affording
maximum
protection
from
acid
rain
damage
if
exposure
is
unavoidable.
SEALING
FUSELAGE
SEALING
Replacement
of
loose
or
missing
sealer
at
skin
joints
prior
to
repainting
is
recommended.

or
sealer
(Item

Holes
or
cracks
to
large
to
be
sealed
with
sealer
may
be
filled
with
Caulking
Compound
(Item

SURFACE
CORROSION
ALUMINUM
CORROSION
Corrosion
may
be
removed
mechanically
or
chemically.
in
mechanical
removal,
it is
essential
that the abrasive
materials
on
the
tool
leave
no
residue
or
particles
that
could
cause
future
corrosion.
An abrasive
previously
used
on
ferrous metals
will contain minute
particles
which
will imbed
in
aluminum
alloys
and
start
a
new
cycle
of corrosion. A steel wire
brush
used
on
aluminium
alloys
will
leave
tiny
particles
sufficient to
initiate
corrosion
of
the
aluminum.
On
clad aluminum
alloys,
use
a
chemical
alkaline
cleaner. Mix and
store
alkaiine solutions
in
plastic,
stainless
steel,
or
glass
containers.
Mask
off
all
dissimilar
metals
as
well
as
all cracks
and sheet
laps. Apply
cleaner
with
a
soft
brush.
Rinse
thoroughly
with
clean
water
and
dry
compressed
air.
