Hi, on my i30 Coupé, which is not even a year old, 3 heating wires in the rear window do not go. This is the second, third and fourth from below. This is of course a stupid place, because this brings with it 2 problems: The already bad view in the Coupé through the rear window is already strongly impaired, if 3 connected wires do not go. There is then a rather wide beam in it, which remains icy. Moreover, exactly in the area the wiper rubber lies on The error can be clearly seen: the conductor tracks are broken, quite wide (about 10 cm), and exactly centered, exactly above each other. You can see exactly how the conductive metal has “broken off”. For me, this is a clear material defect when the conductor tracks are broken so symmetrically to each other and the material is simply detached from the disc. 5 years of Hyundai warranty on the ass, they don’t exchange the disc. The master in the Workshop said that this would look like a scraper scratched over it. Sure, I scrape the inside of the heating wires ice even in winter. Anyway, they don’t want to change the disc, because they fear that they would stay on the cost when the disc is sent to Hyundai and the guarantee is rejected. That’s why I wanted to repair the heating wires with lead silver now, should be quite easy. It can’t get worse anyway, and bad should look Even if there is a color difference in the glass at the end, you don’t see it from the outside through the tinted glass. How this works in itself is already clear to me, however, I wanted to ask if one of you has ever done this before and can share experiences with me. I would be particularly interested in two questions: – Is lead silver only suitable for minor interruptions or does it work reliably and long-term even in the event of long interruptions? Are about 10 cm. – Can someone recommend me a good product with which he has already gained experience? May also be a bit more expensive, I want it to work in the long term and not to be interrupted after a few months.
