Good morning Motor-Talkler, I have a little problem with my paint. Yesterday after the hand wash of my car, I noticed some greyish spots, whose origin and above all type I cannot determine more closely. The spots are smooth and when brushing over with the finger not to be felt, max. small, but that could also be imaginable. The spots are especially on the front above the grill, but also on the door handle or the windscreen. I used the PH Neutral Snow Foam for the hand wash from Valetpro. Then from Mequiars the Wash & Wax. I tried to wipe it gently, but had no chance. My vehicle is a black Hyundai i20 Passion Plus (2018). VG
