My car has a rear spoiler on the trunk which I believe was installed as a dealer option ( I'm the 2nd owner). Its not the one thats kinda squared off on the ends, its more rounded and follows the contour of the rear window. My question is, how is this held on? It looks like it uses double sided tape like the door trim, buy I'm not sure, could be bolted on too. I really havn't had the time to take the inner trunk lid panel off to see if it is bolted down. If it is double sided tape, whats the best way to remove it...heat gun and adhesive remover? I've really never liked the spoiler since I got the car and I imagine it cant help gas mileage either.
