3)
Not
abrading
corroded
surfaces
As
good
as
PC
‐
120
is,
it
can’t
help
bonding
performance
if
applied
to
a
surface
that
is
already
corroded!
Any
surface
that
shows
signs
of
corrosion
should
be
cleaned
by
sanding
or
wire
brushing
to
remove
any
scale
or
corrosion.
After
removal
of
corrosion
then
treat
the
surface
with
PC
‐
120
as
you
normally
would.
4)
Using
PC
‐
120
past
it’s
shelf
life
When
stored
under
normal
conditions
PC
‐
120
has
a
shelf
life
of
12
months
in
an
unopened,
original
container.
PC
‐
120
bottles
are
marked
with
a
lot
number
that
is
a
simple
8
digit
code
that
gives
you
the
date
of
manufacture.
o
“807241”
for
example
is
200
8
,
07
month
(July),
24
th
day
(the
“
1
”
refers
to
the
first
batch
of
PC
‐
120
made
that
day).
Use
the
lot
number
to
make
sure
the
material
is
still
within
shelf
life.
Since
it
contains
isopropyl
alcohol,
PC
‐
120
should
be
tightly
capped
when
not
in
use
to
stop
evaporation.
