- annealing said glass container;
- applying a first coating material to said container at a first location in a container fabrication line subsequent to said annealing step;
- conveying said container to a second location with said first coating material providing surface lubricity;
- and
- applying an acrylic coating layer which is compatible with said first coating material over said glass on said outer surface of said container in liquid form while at least some of said first coating material remains on said outer surface;
