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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality product - perfect for cars with paint protection, including ceramic coatings. *by J***N on January 18, 2026* Great car wash foam.
