basecoat. Always use waxes and polishes that are non-abrasive and made fora basecoat/clearcoat paint finish. White Sidewall Tires Your Buick dealer has a GM White Sidewall Tire Cleaner. You can use a stiff brush with the cleaner. I I NOTICE: Machine compounding aggressive polishing or on abasecoatklearcoatpaint finish may dull the finish or leave swirl marks. 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'' inthe Index.) Aluminum Wheels (If So Equipped) Your aluminum wheels have a protective coating similar to the painted surface of your buick. Don't use strong soaps, chemicals, chrome polish, 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. Foreign Material NOTICE: 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. 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 to remove foreign matter. 250
