Wash the vehicle. To remove dirt, grease and residues from the automatic car wash from the surface, polish the windscreen thoroughly with SONAX PROFILINE Glass Polish using a polishing machine with felt pad. Then, remove the residues with a glass cleaner such as SONAX PROFILINE Glass Cleaner and a Microfibre Cloth Glass. To seal, pour sufficient product onto a Coating Applicator (02377410) and apply the product in a criss-cross pattern to an area of approx. 40x40 cm. Working the coating intensively into the glass improves its durability and effect. Then, apply fresh product to the next section and proceed as described above. When the entire surface of a windows has been treated, start with the next window. Allow the product to work on the glass for 45 to 60 minutes (at room temperature of 20-25 °C). Afterwards, use a new SONAX Microfibre Cloth Glass to polish off the residue to a streak-free finish.
PLEASE NOTE: Ensure good ventilation during use.
