A clear windshield is not just a matter of comfort — it's also about safety. Rain beading off your windshield instantly, without needing your wipers? That's exactly what a good glass coating does. In this guide, we'll explain step-by-step how to correctly apply the Soft99 Ultra Glaco Glass Sealant for a result that lasts up to 12 months.
What is glass coating?
Glass coating is a hydrophobic (water-repellent) layer that you apply to your car windows. Thanks to the nano-coating, water, dirt, and insects adhere less to the glass. The result: better visibility in the rain, less wear on your wipers, and a cleaner window that stays looking good longer.

- ✅ Up to 12 months of water repellency

Step-by-step: applying glass coating
Step 1 — Thoroughly clean the window
Use a good glass cleaner to remove grease, dirt, and old coating. Dry the window completely with a clean microfiber cloth. The window must be absolutely grease-free for proper adhesion.
Step 2 — Polish the window with the Glaco Glass Compound Roll On
Before applying the coating, it is highly recommended to polish the window with the Soft99 Glaco Glass Compound Roll On. This glass polish removes fine scratches, water streaks, and deposits that a glass cleaner cannot remove. The result is a perfect, smooth surface to which the Ultra Glaco adheres optimally.
How to use the Compound Roll On?
- Press the Roll On applicator onto the dry window
- Rub in circular motions over the glass
- Allow to penetrate briefly
- Rinse off the polish residue with a high-pressure cleaner — this is the fastest and most effective way to get the window completely clean
- Then thoroughly dry the window with a microfiber cloth before proceeding
- Repeat if necessary for stubborn stains
Step 3 — Work in dry weather and in the shade
Never apply the coating in direct sunlight or at temperatures below 5°C. Otherwise, the coating will dry too quickly and not adhere evenly.
Step 4 — Apply the Ultra Glaco
Unscrew the cap of the Ultra Glaco and lightly press the built-in applicator onto the window. Move in overlapping, straight lines over the glass — horizontally and vertically. Do not use too much product: a thin, even layer is sufficient.
Step 5 — Allow to penetrate for 3-5 minutes
Wait until the coating becomes slightly hazy — this is the sign that it is starting to harden.
Step 6 — Buff off with a microfiber cloth
Wipe off the coating with a clean, dry microfiber cloth in circular motions. Use a second cloth for the finishing touch.
Step 7 — Allow to dry for 1 hour
Avoid rain or water on the window for at least 1 hour after application. After 24 hours, the coating is fully cured.
Tips for long-lasting results
- Repeat the treatment every 6 to 12 months
- Wash your window regularly with a pH-neutral shampoo
- Avoid aggressive cleaning agents that break down the coating
