i got a carbon fiber roof spoiler for my E60.... will the 3M tape on it be enough to keep it on for a long time?? iv herd some people get the spoiler glue from bmw...
I used urethane silicone from Home Depot. This thing is not coming off!!! It was overkill but I really didn't want this thing flying off on the highway.
I've read good stuff about what BMW sells, Betalink, but I'm not sure how easily removable it is.

I used betalink on my rear spoiler, super messy and strong as cement. My roof spoiler held for almost a year and is now slowly starting to lift up around the edges. I don't think I will use betalink on the roof spoiler unless I have a friend help, if it slides cleanup is a beesh.

I used 3m on my car, and many others, and have yet had one come off. Make sure both the surfaces are super clean, and use the adhesive promoter on the underside of the spoiler.
