UPPER WINDOW and WINDOW SILL Accessory Trim is pre-formed for each vehicle model from a Highly Polished Stainless Steel, with a full coverage 3M acrylic foam adhesive backing to enhance the look of your vehicle. All of our stainless steel products are created from inception to packaging by our team of professionals, on location in Westford, Mass. Upper Window and Window Sill Trim is polished to a mirror shine, giving it a CHROME look. The polished surfaces are protected by a plastic film to be removed after installation. All of QAA's Stainless Steel Trim products are easy to install with a "peel and stick" application of the pre-applied 3M tape on every piece; no drilling, cutting or alterations are required. The bond is water tight and will last a lifetime.
