I wanted to know what kind and where to buy the automotive tape to hold a spoiler on, the stock spoiler that is. I would rather do that than drilling.

 

3M 4229-P is the best tape. Red release liner with the 3M logo silkscreened in white. Beware of imitators. Exterior rated. It's what all the automakers use. By the roll it ain't cheap. See if a body shop will sell you a few feet of 1" wide for a few bucks.
