My shower glass already has water marks — can I still apply it?
If the marks wipe off with vinegar or CLR — yes. Clean first with the included pre-cleaner, then coat. The coating prevents future spots, but it can't undo permanent etching. If glass is permanently cloudy (white haze that won't wipe off), you'll need a glass restoration service first, then we can coat it. Send a photo to our WhatsApp and we'll tell you your glass category — same day.
Do I need to be handy? Can I really DIY this?
The kit is designed for first-timers. If you can spray a glass cleaner and wipe with a cloth, you can apply this. About 5 minutes per panel. Our PJ team is on WhatsApp 9am–10pm if you get stuck — we even do FaceTime walk-throughs if needed.
Will it change how my glass looks?
No. The coating is far too thin to see — below what the human eye can pick up. Glass looks identical before and after, just behaves like glass that repels everything.
Is it the same product used by hotels and skyscrapers?
Same chemistry, same Brisbane factory, same TÜV Rheinland certificate as the version specified for One World Trade Center spire (NYC), Sandals Resorts (Caribbean), Concorde Hotel KL, and Sydney's autonomous metro. The only difference: ours is bottled in DIY kit sizes for hand application.
How long does it actually last?
3-year refill promise for the DIY home kit (free replacement bottle if coating fails — register with a beading video within 30 days of application). The same coating applied via X-Line industrial machine (used on commercial buildings) lasts 10+ years. Hand application is more variable — but with proper cleaning before coating, most home customers see 3–5 years before needing a refresh.
What if it doesn't work? Can I get a refund?
30-day money-back guarantee on sealed kits. 36-month performance guarantee on applied coating — register with a 10-second beading video within 30 days of delivery, and if the coating fails in a specific area later, we'll mail you a matching refill bottle free.
Can EnduroShield restore old glass that's already covered in watermarks?
It can't reverse damage that's already chemically etched in — no coating can. But if the marks still wipe off with vinegar or CLR, you're in the safe zone: pre-clean with the included cleaner, then coat. The coating then prevents new marks from forming. If the glass is permanently hazy (white film that won't wipe), you'll need professional glass restoration first — send us a photo on WhatsApp, we'll tell you your glass category within the day.
Will I still need to clean the glass after applying?
Yes — but with up to 90% less effort. Coated glass still gets body oils, soap residue, and dust. The difference: instead of scrubbing with chemicals, you rinse with water and wipe with a microfibre cloth. Most customers do this once a week and the glass stays clear. We won't say "never clean again" — that's not how surfaces work.
Does the coated glass need any follow-up maintenance or "revitalizer" product?
No. EnduroShield chemically bonds with the glass — it becomes a permanent extension of the surface, not a layer sitting on top. Unlike some competitor coatings that need a top-up every 6 months, this one is set-and-forget for the 3-year refill window. The only "maintenance" is your normal weekly wipe-down with water + microfibre.
How should I clean the glass after it's coated?
Microfibre cloth + water for daily use. For heavier cleaning (soap scum buildup after a few weeks), use a mild detergent OR a 1:4 white vinegar dilution. Avoid: abrasive scrubbers, ammonia-based glass cleaners, bleach, or any acidic descaler — these wear the coating prematurely. Our after-care guide is on /maintenance/ if you want the full list.
Can I apply EnduroShield to my old shower screen or bathtub? (not just new)
Yes, as long as the surface is clean and not permanently etched. We've coated shower screens 10+ years old, bathtubs, glass partitions, even reflective surfaces. The trick is the pre-clean — the kit's included cleaner removes existing water spots and soap film so the coating bonds directly with the glass. If you're unsure your glass is restorable, send us a photo on WhatsApp before ordering.
