Each KEEP Maintenance folder includes (10) applications of GlassParency KEEP along with detailed instructions to rejuvenate the hydrophobic performance of glass that has previously been treated with GlassParency's Glass Treatment.
Store the Maintenance Folder in your trunk or glove box to re-apply as needed. When re-applied once every 3 months, you'll have enough KEEP applications to refresh the water repellency of your glass for the next 3 years!
