g. Painting the Repair:
1. An important
factor
in obtaining
a quality paint
finish is the
proper preparation
of the
repair
and
surrounding
area
before applying
any
paint.
2.
It is recommended
that parts
be cleaned
prior to painting
with a
commercial
cleaner or a
solution
made
from one-fourth
cup of
detergent
mixed with
one gallon
of water.
3.
The paint
used for coating
thermoplastic
can be either
lacquers or
enamels depending
on which
is
preferred by
the repair facility
or customer.
(See
NOTE.)
- NOTE-
It is extremely
important
that solvent
formulations
be considered
when selecting a paint,
because not all lacquers
or enamels can be
used
satisfactorily
on thermoplastics.
Some
solvents used
in the
paints can significantly
affect and degrade the
plastic properties.
4.
Another important
matter
to consider is
that hard, brittle
coatings
that are usually
best for
abrasion
resistance
should not
be used in
areas whick
incur high
stress, flexing
or impact.
Such coating
may
crack,
thus creating
a weak
area.
