White Sidewail Tires
your Buick dealer has a GM White Sidewall Tire
Cleaner. You can use a stiff brush with it.
Weatherstrips
These are places where glass or metal meets rubber.
Silicone grease there will make them last longer, seal
better, and not stick or squeak. Apply silicone grease
with a clean cloth at
least every six months.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
damage your vehicle's finish if they remain on painted
surfaces. Use cleaners that are marked safe for painted
surfaces for these stains.
Finish Damage
Any stone chips, fractures. or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer's body and paint shop.
