Finish Care
Occasional waxing or mild polishing of the vehicle by
hand may be necessary to remove residue from
the paint finish. GM-approved cleaning products can
be obtained from your dealer. See Vehicle Care/
Appearance Materials on page 5-91.
Notice: Machine compounding or aggressive
polishing on a basecoat/clearcoat paint finish may
damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint finish on your vehicle.
The vehicle 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.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap,
bird droppings, chemicals from industrial chimneys,
etc., can damage the vehicle’s finish if they remain
on painted surfaces. Wash the vehicle as soon
as possible. If necessary, use non-abrasive cleaners
that are marked safe for painted surfaces to remove
foreign matter.
Exterior painted surfaces are subject to aging, weather,
and chemical fallout that can take their toll over a
period of years. To help keep the paint finish looking
new, keep the vehicle in a garage or covered whenever
possible.
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap, or other material may be on the blade
or windshield.
Clean the outside of the windshield with a glass
cleaning liquid or powder and water solution. The
windshield is clean if beads do not form when it is
rinsed with water.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by
wiping vigorously with a cloth soaked in full-strength
windshield washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
