I have a few questions, if you don't mind.
I have tried and failed many times to repair these. Latest attempt was double stick tape, failed in days. Should have guessed.
I believe my failure is related to technique, and not adhesive.
My first question is: Do you garage your car the majority of the time, or do you live in an area where you do not regularly see high temperatures, or much direct sunlight? I believe that my outdoor parking and high levels of sun, and relatively high heat might be contributing to higher failure rates.
In my previous attempts (especially with the 3M weatherstrip adhesive, and later with epoxy), I had the window down, and used blue painters tape to secure the trim to the car. I am wondering if the window should be up, that way the trim seats more naturally with the position of the glass. Same goes for the door on the sides. I secured the trim with tape, with the door opened until the adhesive cured. I am thinking it would seat more naturally with the door closed.
Can you elaborate on your technique that has worked successfully?
