Something* got all over my X3 (except for the wheels and textured parts) and nothing I tried removed it except for vigorously scrubbing with compound. My friend brought me his clay bar and some detail spray from his shop. If that doesn't work I am going to file a claim because I don't have the patience to deal with it.
*can't figure out if it's paint overspray, a contaminant from road salt, or possibly some kind of debris from the car wash. I went to a regular, non-touchless one 3x 😞
