I just put a ceramic coating on my Performance 3, and am really happy with it. But I still want to do a little more than just hose it off. As good as it is, some dirt will stay on it with the garden hose, particularly nearer the bottom of the car. I was thinking about getting a Sun Joe electric pressure washer because I like the way you can mix in a car cleansing mix while washing the car. Quick question for the group is whether it is OK to pressure wash a car with ceramic on it? Thanks
