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.
 
I have used Carpro Ech20 over 303 graphene occasionally with great results. Si02 in this dilution causes no problems.
 
Shouldn’t be any issue. I would think ECH2O would be better than using ONR, as ONR leaves polymers behind that could mask the desired characteristics of your 303.

Keep an eye out for the new McKees 37 Graphene Rinseless Wash that was just announced at SEMA (I believe). You can mix that up at a waterless wash dilution ratio if you want. Would make a nice complement to your 303 I would think…

I'm with BadgerRivFan - I wouldn't go ONR. I ended up with more road film bonding to the car when I tried it.

I like the Griot's Brilliant Finish Rinseless for a leaves nothing, but I would think as long as Ech20 plays well in the cool weather that should be a fine way to go.

What part of Minneapolis are you in? Could try and get you a sample if you wanted to try it out.
