The invention relates to a bent glass sheet, at least one of the main faces thereof being activated. The activation can be performed, for example, by means of direct frictional abrasion of the surface of the glass. The inventive method preferably comprises the use a closed-loop abrasive strip which passes across the surface of the glass. After activation, a hydrophobic layer can be deposited, for example, from a fluorinated silane. The glass coated with a hydrophobic layer can be used as glazing for a motor vehicle.
