If you were to add a ceramic coating to your Porsche, it would make the car incredibly easy to clean. When cleaning, about 80-90% of all the dirt comes off with just a pressure washer, making your washing time a breeze so that you can get on to more important things!
Use a foam gun if possible and wash panel by panel up to down and clean your wash mitt with a grit guard after each panel.
It always doesn’t hurt to continue to use the 2 bucket system to ensure you don’t scratch the ceramic coating and maintain it for the long haul.
