Review: no lo recomendaría... - He probado este producto en dos ocasiones. La primera lo puse sin un prep y sin algún producto que quitara el poco sarro que existía. Duro una semana y un par de días. Lo estoy usando en época de lluvias. La segunda ocasión prepare los cristales perfectamente y lo aplique con pads y suedes. Fue mucho mejor la aplicación. El efecto hidrofobico fue excelente la primera semana, la segunda semana disminuyo considerablemente, me parece que este producto no dura mas de unas 3 semanas. Por el tiempo de aplicación considero que no vale la pena en absoluto. Insisto los primero 3 días funcionó bastante bien en carretera, despues de la primera semana se ha ido degradando considerablemente. Finalmente, el producto inicia su efectividad a partir de 80-90 km/h, arriba de 100 es muy buena, pero antes de 80 es mínimo el efecto. Lo aplique tambien en un casco de moto, me parece que funcionará bien, al menos por un tiempo. No lo recomendaría.

Saw a review and decided to try it. For the price it's a no brainer. I saw comments that it was difficult to remove however I did mine on a cloudy day with temps in the low 60s. I used a new microfiber cloth from Costco to remove and had no issues. Follow the instructions to shake well and use a small amount and wait the 15 minutes before buffing. ## Frequently Bought Together - Gtechniq G5 Water Repellent Coating for Glass and Perspex 100ml - 3 to 6 Months, Beads Water for Car Windows, Marine Glass - USANOOKS Microfiber Cleaning Cloth Grey - 12 Pcs (12.5"x12.5") - High Performance - 1200 Washes, Ultra Absorbent Microfiber Towel Weave Grime & Liquid for Streak-Free Mirror Shine - Car Washing Cloth - Invisible Glass 91164-2PK 19-Ounce Foam Cleaner for Auto and Home for a Streak-Free Shine, Deep Cleaning Foaming Action, Safe for Tinted and Non-Tinted Windows, Ammonia Free, Pack of 2 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/674685402-gtechniq-g5-windshield-water-repellent-coating-on-glass-and-perspex](https://www.desertcart.jp/products/674685402-gtechniq-g5-windshield-water-repellent-coating-on-glass-and-perspex) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-15*
