Soft99 Ultra Glaco 70ml | 12-Month Windscreen Rain Repellent Coating
Soft99's flagship windscreen coating — builds an ultra-hydrophobic silicone layer on glass that repels rain, sleet and road spray for up to 12 months per application.
What you're buying. One 70 ml bottle with the felt applicator built into the cap. That treats a windscreen several times over — most people get two to three years of applications out of a bottle, not one.
The chemistry. Ultra Glaco is a silicone-polymer glass coating. The active molecules bond covalently to the silicate in your windscreen, creating a cross-linked hydrophobic film with a water contact angle around 110–120°. Translation: water beads up into tight droplets and rolls off at 50 km/h and above — so in moderate rain you barely need wipers.
Why it matters at night. A hydrophobic windscreen dramatically improves safety at night and in heavy rain — headlights scatter less off a beaded, mobile water layer than off a thick sheet of water clinging to untreated glass.
How to apply. Clean glass thoroughly with a dedicated glass cleaner — any oil, wax or old rain-repellent residue will block bonding. Dry completely. Apply Ultra Glaco in straight overlapping passes using the included felt applicator. Wait 5–10 minutes to flash off, then buff off residue with a clean microfibre.
