I NOTICE: Machine compoundingor aggressive polishing on a basecoat/clearcoat paint finish may dull the finish or leave swirl marks. White Sidewall Tires Your Buick dealer has a GM White Sidewall Tire Cleaner. You can use a stiff brush with the cleaner. 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 & Lubricants" in the Index.) Aluminum Wheels (If So Equipped) Your aluminum wheels have a protective coating similar to the painted surface of your car. Don't use strong soaps, chemicals, chromepolish, abrasive cleaners or abrasive cleaning brushes on them because you could damage this coating. After rinsing thoroughly, a wax may be applied. 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. If you have aluminum wheels,don't use an automatic vehicle wash that has hard silicon carbide cleaning brushes. These brushes can take off the protective coating. 249
