Where I work in my new job, I get a thin layer of cement dust on my car. Some days are worse than others, depends whether we have a ship in or not and whether there is a high wind.
I have topped up the polish on the car since I have been there, and it does not look like it is doing any damage.
Do you reckon it will be OK? I have been trying to wash the car once a week to get the dust off, even if it is a quick rinse.
