I had this on my previous X3 and recently on my Audi Q5. So perhaps not abnormal.After a rain or a car wash, there are water drip marks stretching down the door under the mirrors and door handles. This does not happen on my wife's 2018 or previous 2015. Is this normal?
Now there's a smart man! I do the same with my ceramic coated 400 vert. I just use the hose and any stuff on the car just rolls off and then it is blown dry! Just like Joe's car wash!!I use my yard blower to blow off my cars, and bikes after washing Does a great job getting rid of the excess water in the crevasses. Then I just towel dry the drips if needed.
