I have a 2017 Subaru Legacy (grey) that has etched into the paint. The car belongs to my son who had no clue about the importance of getting the bird droppings off ASAP. It is now too late and will not come out. I really do not want to wet sand the spots. I have a DA buffer, I am just not sure which product will work. I have heard that a hair dryer will work as well. I am not sure that is true.
