Hmmm...apparently I can't link photos directly from my flickr account???
Try this link to the Flickr set. It contains all the original pictures fron the post and some additional ones. I can say that using the 3M tape was the right choice for me. After approximately 16 months, the spoiler is still mounted rock solid since the first day of installation.
Sorry, it took so long to get these pictures back up. Enjoy!
