Clean glass thoroughly using AutoServe Shampoo MW. Squeegee off excess water and allow drying completely, ensuring that glass is moisture free.
Soak a small clean soft cotton cloth with AutoServe Water Repellent. Apply the solution by close vertical and horizontal strokes to cover the complete surface without leaving gaps. Allow the solution to remain in contact for at least 10 minutes. Buff down the applied surface with a small piece of soft clean and dry absorbent cotton cloth ensuring an invisible, even layer of coating over the total glass area. Allow the buffed layer of coating to dry before allowing contact with water.
Caution : For best results AutoServe Water Repellent should be applied when the glass is not wet or hot; and away from direct sunlight.
