Abstract
A window channel receives a slidable pane of window glass within a gap. The glass slides in contact with areas which are coated with low friction material which is applied by sintering. For example, the sintered material may be powdery polyurethane, polypropylene or polyamide. The sintered powders may be transparent and may be applied after the areas have been coated with a solvent or primer. Using similar materials, but with colored powders, the exposed surfaces of door and other seals may be provided with a colored coating.
