I have applied the Graphene Ceramic coating. The three photos show after. Prep was wash, clay pad, polish with M205. Graphene was applied over a two day span. The coating has been on for about a month. I was using Meguiars Gold class soap in foam cannon. I then switched to Griots Garage brilliant shine soap in foam cannon. The last wash, I tried to use the Graphene boost. The last week and a half, smoke covered Spokane. I am unsure if the smoke, ash dust affected the Graphene ability to shed rain water.
