Soft99 Glaco Range Explained: Ultra Glaco vs DX vs Roll On vs Q vs Blave
For maximum durability the best Soft99 glass water-repellent is Ultra Glaco (up to ~12 months, PTFE/Fusso, felt-bar applicator). If you want the easiest modern application choose Glaco DX (~4 months, cures in ~5 minutes). All Glaco variants are ready-to-use and only bond to clean, dry, decontaminated glass.

| Product | Durability (mfr) | Application | Best for |
|---|---|---|---|
| Ultra Glaco | Up to ~12 months | Built-in felt bar tip, keep glass dry 12h | Longest life, highway drivers, "fit and forget" |
| Glaco DX | ~4 months | Movable felt head, ~5 min cure | Newest, easiest; city / low-speed rain |
| Glaco Roll On | Several months | Classic felt roll-on | The original repellent; simple, affordable |
| Glaco Q | ~3 months | Large felt "iron" applicator, no cure | Clean + coat in one step |
| Glaco W-Jet | Weeks–months | Spray onto wet glass | Fastest top-up when weather turns |
| Glaco Blave | ~3 months | Apply & wipe with microfiber | Glass and clear plastics (lights, visors) |
Ranked picks
- Ultra Glaco — the durability benchmark. A PTFE/Fusso fluorine coat rated up to ~12 months; rain sheds from roughly 45–60 km/h. Best if you drive at speed and want the fewest re-applications. Keep glass dry 12 hours to cure.
- Glaco DX — the newest and easiest. SARF chemistry bonds in about 5 minutes and the hydrophobic effect starts around 45 km/h, so it suits mostly-city driving. Shorter life (~4 months) is the trade-off for convenience.
- Glaco Roll On — the classic felt roll-on and the simplest, most affordable way into Glaco. Note this is the water-repellent, not the Glaco Glass Compound Roll On prep cleaner.
- Glaco Q — cleans and coats in a single pass with a large felt applicator; no curing wait. Good when you want to skip a separate prep step, at the cost of ultimate durability.
- Glaco W-Jet — a pressurized spray applied to wet glass; the fastest method for a quick top-up when rain is coming, though it lasts the least.
- Glaco Blave — the most versatile: works on glass and on clear plastics (headlight lenses, visors, helmet shields) where standard liquid wipers fade quickly.
How to choose
Pick on two axes: durability vs. application effort, and surface. Ultra Glaco lasts longest but needs a careful two-pass application and a 12-hour dry cure; Glaco DX and Q trade some longevity for a fast, near-foolproof application; W-Jet is the quickest but shortest-lived top-up. Choose Blave if you also want to coat clear plastics. Whichever you pick, durability is set by prep — glass must be washed and decontaminated first. Use the Glaco Glass Compound Roll On or a glass polish, and only ever apply to clean, dry glass. For side mirrors, Glaco Mirror Coat Zero is purpose-made.
FAQ
Which Soft99 Glaco lasts the longest?
Ultra Glaco. Soft99 rates it up to about 12 months — roughly six times a standard glass coat — thanks to its PTFE/Fusso fluorine layer. Glaco DX lasts ~4 months; Q, Blave and W-Jet are shorter.
What's the difference between Glaco Roll On and Ultra Glaco?
Ultra Glaco is the long-life Fusso/PTFE coating (up to ~12 months) applied with a felt bar tip. The classic Glaco Roll On is the original, simpler felt roll-on repellent — easier to apply but shorter-lived.
Do I need to prep the glass before applying Glaco?
Yes. All Glaco variants only bond to clean, dry, grease-free glass. Decontaminate first with the Glaco Glass Compound Roll On or a glass polish; skipping prep is the main reason coatings fail early.
How fast do you have to drive for Glaco to repel water?
Water begins to sheet off at roughly 45 km/h (DX, W-Jet) up to ~60 km/h. All Glaco coatings self-clear best at speed; below that you may still need wipers in heavy rain.
