Best Windscreen Rain Repellent Malaysia 2026

A rain repellent coating is the cheapest monsoon upgrade in Malaysian driving. It makes water pull into beads and blow off the glass, so your wipers keep a clear view at highway speed instead of smearing a sheet of water across the windscreen. Our pick is Soft99 Ultra Glaco for the coating that lasts, the QNS spray for the easiest application, and the BIG+ coating for a fast, even film.

Introduction

A Malaysian afternoon downpour arrives with almost no warning: the sky goes dark, the wipers go to their fastest setting, and the car in front disappears into a blurred sheet of water. The variable that decides whether you can still drive comfortably is the glass, not the wipers. An untreated windscreen lets water spread into a film that the wipers push around; a coated windscreen makes the same water bead up and get peeled off by the airflow.

We compared the three best-selling rain repellents on Lazada Malaysia — a spray, a silicone-based glass coating and a Japanese paste coating — to show which format suits which driver, and how to apply each one so it lasts through the monsoon.

1. QNS Rain Repellent Windscreen Coating

This is the entry point. The QNS rain repellent is a spray you mist onto the glass and wipe off, which makes it the fastest way to find out what a coated windscreen feels like before you commit to a paste. The listing sells it as a rain repellent and anti-fog coating for car windows, and it is the product to reach for when you want the windscreen, the side glass and the mirrors done in ten minutes. Because a spray carries less solid material than a paste, expect to reapply it more often — which is exactly what you want if you are coating the side windows and mirrors as well as the windscreen.

• Pros: Spray format, no buffing paste to work in; sold as an anti-fog and rain repellent in one; covers the windscreen, side windows and mirrors; cheapest way to try a rain repellent coating
• Cons: Spray coatings wear off faster than a paste coating; needs reapplying more often than Glaco

Verdict: Easiest to apply — spray on, wipe off, and the glass starts beading straight away. The best first coating, and the one to keep in the boot for a top-up.

2. BIG+ Rain Repellent Car Windscreen Glass Coating

The liquid coating is the format to reach for when you want an even film fast. BIG+ Rain Repellent is a silicone-based glass coating — the brand describes it as clear silicones in a fast-drying solvent that leaves a transparent, slick protective film on the glass, which is exactly the behaviour you want on an exterior windscreen. Water beads on it, the wipers clear it, and at highway speed the airflow peels the beads off. There is no paste to work in and nothing to mask off: apply it to clean, dry glass, let it dry, wipe it off. The 100ml bottle covers a windscreen many times over, so one bottle carries a household through several monsoons. The trade-off is durability — a silicone film like this wears off faster than a paste coating, so plan to reapply more often than you would with Glaco.

• Pros: Silicone-based coating leaves a clear, slick protective film; fast-drying formula, no paste to work in; 100ml bottle covers the windscreen many times over; no aerosol overspray to mask off
• Cons: Wears off faster than a paste coating like Glaco; needs a clean, dry windscreen before it will bond

Verdict: Best for a fast, even film — a silicone glass coating that dries in minutes, from a bottle that lasts all year.

3. Soft99 Ultra Glaco Glass Coat Rain Repellent

This is the one we would put on our own car. Ultra Glaco is a paste glass coating from Soft99 in Japan, and it is the format that survives real conditions: the solids bond to clean glass and the beading lasts far longer than a spray. The listing claims up to a year of rain repellency on a windscreen, and the 70ml jar holds enough for several applications. It ships with the applicator cloth, so the box is everything you need. The cost is effort — apply it in overlapping passes, let it haze, then buff it off with a dry microfibre cloth, and the glass has to be perfectly clean and dry first.

• Pros: Paste glass coating, the longest-lasting rain repellent format; listing claims up to a year of beading on a windscreen; made in Japan, applicator cloth included; 70ml jar covers several applications
• Cons: More effort: apply, let it haze, then buff off; needs a perfectly clean, dry windscreen to bond properly

Verdict: Our pick — the coating that lasts the longest, which is the whole point when the monsoon runs for months.

Buying Guide — How to Choose a Rain Repellent in Malaysia

1. Pick the format by effort, not price. Paste (Glaco) lasts longest and takes the most work. A liquid coating (BIG+) is fast and even. A spray (QNS) is the simplest and needs the most reapplication.
2. Clean glass before anything else. A coating bonds to glass, not to road film. Wash the screen, then wipe it with rubbing alcohol or a glass degreaser and let it dry. Skipping this is the most common reason a coating “doesn’t work”.
3. Coat the side glass and mirrors too. Water on the door glass is what blurs your mirrors at traffic lights, where there is no airflow to blow it away.
4. Apply in the shade. Coating hot glass in direct sun flashes on and streaks. Do it in the evening or in a shaded porch.
5. Don’t coat the interior. Rain repellent is for the outside face of the glass only. Interior fogging is condensation — fix it with the air-con on demist and clean interior glass.
6. Reapply when the beading dies. When water stops beading and starts sheeting, the coating is spent. Top up a spray every few weeks; a paste coating lasts months.

Frequently Asked Questions

Does a windscreen rain repellent actually work?

Yes, and it’s one of the few car care products with an obvious effect. A glass coating changes the surface tension of the glass so water pulls into beads instead of spreading into a sheet. Above roughly 60–80 km/h the airflow peels the beads off, so your wipers clear the windscreen at speeds where an untreated screen would smear.

Which rain repellent format lasts longest — spray, liquid coating or paste?

Paste coatings such as Soft99 Ultra Glaco last the longest, because the solids bond to clean glass and survive wiper traffic and heavy rain. Liquid and spray coatings are quicker to apply and cheaper per bottle, but they wear off faster and need reapplying more often.

Can I use rain repellent on the side windows and mirrors?

Yes, and you should. Water on the door glass is what blurs your mirrors and side view in a Malaysian downpour. Coating the side windows and the wing mirrors keeps them clearer at traffic lights, where there is no airflow to blow the water away.

Why does my windscreen fog up inside after I apply a rain repellent?

Rain repellent goes on the outside of the glass only. Interior fogging is condensation from humid cabin air, and it is fixed by the air-conditioning on the demist setting, not by an exterior coating. Keep the interior glass clean too — an oily film on the inside fogs far faster.

How do I apply a rain repellent coating properly?

Wash the windscreen, then wipe it with a grease remover or rubbing alcohol and let it dry fully. Apply the coating in overlapping passes, let it haze, then buff it off with a clean microfibre cloth. Never apply in direct sun or on hot glass, and avoid washing the car for a few hours afterwards.

Will rain repellent stop my wipers from chattering?

No. A coating helps water leave the glass, which reduces smearing, but wiper chatter is caused by worn or contaminated rubber blades and by wax residue on the glass. Replace the blades and degrease the screen if they skip.
