Good day, I bought an E90 a few months ago and quickly noticed that it was only washed in the wash road and accordingly the surface of the paint looks like this (light fine scratches in the paint). So I wanted to polish the car anyway and have it polished soon in the spring. But what I noticed are these “flakes” on the bonnet (see picture attached), which do not disappear after a normal laundry from me, look like water What could that be? Tree resin? I don’t know, don’t know me well. Hope one of you can help me! Thank you very much.
