Audi S4 Cabriolet Top Repair - Glass Coming Unglued! Fix it Yourself for $5.
Audi convertibles apparently come with a glue that last just longer than the warranty. A common problem is that the glass and the top start to separate. The factory repair calls for top replacement - a $5000 repair. This video shows how the top was successfully fixed with $5 of silicone. I will check back in 6-12 months and let you know how it is holding up.
UPDATE 12-2013 - Still holding up well. I did the other corner, but didn't clean it as well with mineral spirits. It failed. I cleaned it up again and now it is fine.
