Glass Sealants

Glass sealants make rain bead on the glass and blow off as you drive, so you see more and need the wipers less. The range covers wipe-on rain repellents such as Invisible Glass Rain Repellent, glass cleaners that leave a repellent layer behind, and interior anti-fog treatments.

How to choose

• A dedicated repellent such as Invisible Glass Rain Repellent goes on clean, dry glass and lasts longer than the light layer a repellent cleaner leaves, and Glass Coatings cure onto the glass and last longer still.
• Clean-and-repel sprays such as Stoner Invisible Glass Clean & Repel, CarPro Clarify Phobic and NowRevive Hydrophobic Glass Cleaner clean and top up in one wipe.
• For misting, CarPro Fog Fight goes on the inside of the glass.

Good to know

• Anything left on the glass gets sealed in and smears in the rain. Remove water spots and old film first with Glass Polishes.
• If the wipers judder afterwards, buff off leftover residue with a dry microfibre. Worn blades cause the same judder.
• Do the side windows and door mirrors too: they have no wipers, so that is where a repellent helps most.

What is the best sealant for car windows?

It depends how long you want it to last. A wipe-on repellent such as Invisible Glass Rain Repellent lasts longer than the light layer a clean-and-repel spray leaves, and glass coatings last longer still. Whichever you choose, it goes on clean, dry glass.
