I have 2 vehicles now in my garage that have 303 Graphene coating on them. I live in Minnesota and my normal winter washing process is, quarter wash to get big debris and most salt off. Follow that with a waterless wash in my heated garage. I have used CarPro EcH2o for the last few years, and like it. It does contain a amount of Sio2. I'm curious if using this will affect the graphene coating? For othis reason im thinking bout switching to Optimum just to be on the safe side. Let me know your thoughts, or if you have other recommendations.
