Just wipe with a supplied microfiber cloth spray and last 12 months!
Coating becomes even stronger when applied repeatedly.

Directions to use:

• Work in a place that is well evoked.
• Do not use while driving.
• Since it will be difficult to spread or spread unevenness, do not use it when left for a long time while spraying or when it is hot in the scorching sun or the glass is hot.
• If it adheres to other than the glass surface, wipe it off with a towel etc moistened with water.
• Do not use during rainy weather.
• When the temperature is low such as in the winter, use the defroster etc. before warming the glass surface etc.
• If the wiper blade is deteriorated or the pressure is high, the wiper may malfunction (chatter), so replace the blade or drop the coating if it does not go straight.
• Because it may causes scratches, do not try it in strong winds or sandy places.
