Checking Window Glass

Information 

• The hydrophobic coating is extremely durable. If the hydrophobic characteristics are reduced, a new coating can be applied to the windows without any special measures. 
• Check whether new coating needs to be applied by examining drops of water on the windows. 

  Spray on water using a water spray bottle with an atomizer and check the hydrophobic coating by examining the drops.
