I reatched my stock spoiler today, it was coming loose all over from the 2 sided tape giving out. Anyways, I used some expoxy that you have to mix and put it on the spoiler and the trunk making sure not to get it all over. I then set a towel over the spoiler and stacked 25 pounds of weights on one side and a couple 12 packs (soda of course) on the other. I let it sit for a few hours and she's as good as new.
