them. Use wax after you clean them. Also, don't use
abrasive cleaners or cleaning brushps on them - you
could damaee the proutive caating.
Your Buick dealer has a GM White Sidewall Tire
Cleaner. You can use a stiff brush with it.

These are places where glass-or metal meets rubber.
Silicone grease there will make them last longer, seal
better, and not squeak. Apply silicone grease with a
clean cloth at least every

repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.

road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
