with garages' suggestions. Never thought that fixing a Mirror on the Windscreen will be so difficult. The mirror just does not stick inspite of all cleaning procedures. The maximum the mirror has stayed stuck is 3 months. There must be some better ways to fix the mirror. All kinds of glues available in the garages were used with varying results. There is no glue strong enough to hold the mirror in place for more than 3 months.
Have tried the vaccum mirrors but they don't provide the visual fields at all and nothing is visible because the adjustment is very limited.
I will greatly appreciate advice in fixing the mirror permanently.
In the past, it happened to a different car and the fixing of mirror was permanent and it never came off.
The current problem seems to be a specific problem with a Daewoo car.
Awaiting any suggestions.
