Cleaning the Outside of Your Buick The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Finish Care Occasional waxing or mild polishing of your Buick by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your dealer. (See "Appearance Careand Materials'' in the Index.) Your Buick has a "basecoat/clearcoat" paint finish. The clearcoat gives more depth and gloss to the col.ored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish. Washing Your Vehicle The best way to preserve your vehicle's finish is to keep it clean by washing it often with lukewarm or cold water. Don't wash your vehicle in the direct rays of the sun. Don't use strong soaps or chemicaldetergents. Use liquid hand, dish or car washing (mild detergent) soaps. Don't use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or a 100% cottbn towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle. NOTICE: Machine compounding or aggressive polishing on dull the a basecoatklearcoat paint finish may finish or leave swirl marks. 6-47
