I have recently started a business detailing cars. I did a 2016 charger last week. Today it has been raining off and on and the owner messaged me quite upset that the water is beading on the hood of the car ( which is flat) and says water should never do that. I tried to explain to him that there is no where for the water to go when the vehichle is sitting. Does anyone have any suggestions on how I can explain to this guy that's there is nothing wrong. Worst part is I offered to do this guys car so I had pictures for my Instagram account so he didnt pay a fine but is now irate.
