Not if you want it to stay on.
Go to the parts store and get some 3M automotive trim tape.
Clean both surfaces by spraying down a rag with brake parts cleaner and wiping the surfaces.
Apply the tape to the spoiler.
Peel the backing off the tape, and place the spoiler in position.
Make sure the spoiler is the correct position.
Because once the tape comes in contact with other surface . it’s nearly impossible to remove.

Tester, I love you. You are a gentleman and a scholar.
no, that’s my other vehicle. I got a remanufactured tranny put in. It’s working well now. Thank you!
