The clear on "frozen" finishes meet the same standards, and G Wash is recommended for use with their coatings. **Q: Is this body shop safe ? Can I use this in fresh paint .. and are there any silicones in it** A: As far as I know it is since they are no abrasive in it however just to be sure you can contact a ceramic pro coating specialist, go on youtube or just google it. I use it because I had my car ceramic coated and it does not damage the coating. I would have to say it is safe to use after the paint is cured. **Q: How much do you add to a foam cannon? My chemical guys Cannon has a line on the side but it seems like a ton of product.** A: Check your settings. There are also inserts to reduce the amount of water going through the cannon to make soap use efficient if you have too powerful of a pressure washer ## Frequently Bought Together - Gtechniq - W1 GWash - Big Foam Content, Breaks Bond Between Dirt Film & Paint; Minimal Surface Abrasion; Gloss Retention; Reduced Scratching (1 Liter) - Gtechniq W6 Iron and General Fallout Remover for Cars, Brake Dust Degreaser and Cleaner for Wheels, Rims and Paintwork, Safe on Coatings, 500ml - Gtechniq WM2 Microfibre Wash Mitt - Ultra Low Friction Washcloth, Soft Glide Minimises Swirl Marks - Holds Maximum Volume Of Soap Suds, 100% Split Varied Length Polyester Strands For A Quick Easy Wash --- ## 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.hr/products/81529517-car-shampoo-auto-w1-gwash-shampoo-for-cars-dirt-stain](https://www.desertcart.hr/products/81529517-car-shampoo-auto-w1-gwash-shampoo-for-cars-dirt-stain) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-25*
