A few months ago, I was disturbed by stubborn “Fliegendreck” at the roof edge above the windscreen of my V70 (III). But even after prolonged soaking and polishing, the spot did not go away. If you look at it more closely, it is probably a matter of rusting. Lackabplachers are not visible at the roof edge, when the area is enlarged strongly, the place shows rust bubbles bursting up. Meanwhile, the first spot has become significantly larger and five more have joined. From week to week, it seems to be more to feel better at first than to see. According to Volvo, these are impacts of foreign bodies, so that there is no reason for any remedy from there. Stone strokes, according to my experience, lead to paint chippings, which then rust from the blank sheet – unless you do anything. But that without visible impact, just blooms from below??? Does anyone know the problem (my V70 had first registration 03/2010 in Sweden; varnish is Caspian blue metallic) or does anyone have an explanation for this unpleasantly rust-like Volvo?
