Buick’s Engineer-Approved Machine Glaze was an auto wax available at your local Buick dealership to keep your car in tip-top shape! The 6-ounce plastic jar features a tin screw lid with the words “Buick Beauty Glaze” in red letters. Some staining is on the lid from wax residue over the years. The Buick logo with “Machine Glaze” and the part number are on the front of the plastic jar. The directions for use are on the back, and the bottom has an excellent embossed “Buick” script. 20809-ET
