Weatherstrips
Silicone grease on weatherstrips will make them
last longer, seal better, and not stick or squeak.
Apply silicone grease with a clean cloth at least
every six months. During very cold, damp weather
more frequent application may be required. (See
"Recommended Fluids and Lubricants", in the Index.)
-Cleaning the Outside of Your Pontiac
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
.
The best way to preserve your vehicle's f i s h
is to
keep
it clean by washing it often with lukewarm or cold water.
Don't wash your vehicle in the directrays of the sun.
Don't use strong soaps or chemical detergents. Use
liquid hand, dish or-car washing (mild detergent) soaps.
Don't use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed to dry on
the surface, or they could stain. Dry the finish with a
soft, clean chamois or a 100% cotton towel to avoid
surface scratches and water spotting.
High pressure car washes may cause water to enter your
vehicle.
Finish Care
Occasional waxing or mild polishing of your Pontiac by
hand may beaecessary to remove residue from the paint
finish. You can get GM-approved cleaning products
from your dealer. (See "Appearance Care and Materials"
in the Index.)
Your Pontiac has
a
"basecoat/clearcoat" paint finish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes
that
are
non-abrasive and made for a basecoat/clearcoat paint
finish.
NOTICE:
Machine compounding or aggressive polishing on
a basecoat/clearcoat paint finish may dull the
finish or leave swirl marks.
