So because it's made by 3M, nothing could go wrong? They aren't perfect, as their 9 million dollar settlement to the U.S. government for providing defective earplugs to the U.S. Military shows. And not long before that, an 8 million dollar settlement in the state of Minnesota.
I also visited the site you linked, which gives you the option of entering what you are gluing together, "this" to another, "that". I entered "fabric" (felt was not an option), to "metal". The website said the best glue to use was 3M's "77", which is their regular strength contact cement.
Looking into it further, "glue this to that" isn't even a product, it's a website. So, I'm not sure how you have used it exactly.
The original poster was looking for suggestions on a specific topic, from people who have had actual experience in that field. That's what this site is for.
