Hey guys I removed my spoiler today just thought I'd help you guys that are thinking about doing it.
It took me about 20 minutes and some patience.
I used 4 mud spreaders and a pieces for black plexiglass. I grinded the corner of the plexi to a fine point and taped both sides of the gate. I slowly worked it all the way across and back a few times placing the spreaders where it had come up to keep from scraping or flexing. There is glue and fiberglass spread across the whole thing so you will need to grind it off to paint or put a cap on the gate. 20 minutes of finessing it and it practically fell off no cracks no paint chips. I think keeping slight pressure spread across the entire spoiler made the job accident free. I was dreading removing it because ive seen all the horror stories about them snapping. Its not hard as long as you have some patience. Hope this helps you guys!
I will post pictures soon
