Hello, last week my Opel Omega B, year 2003 seems to have torn the windshield at the lower right corner for inexplicable reasons. At the disc exchange it was then found that the lower right and left body corner is rusted more strongly and thus got tension on the windshield, which caused the crack. Before the disc exchange was recommended to me to have the rust corners thoroughly removed. Which I then for cost reasons only I had known nothing about rust guarantee until now. Before I went to the Opel workshop I would have liked to have an exchange of experience in this matter as a) I already had the new disk mounted and b) I did not have my checkbook completely. Thank you in advance.
