I got one a month ago from Southwest's closeout. Is there something to spray on the adhesive before installing it so I can slide it around a bit to get the correct position? Otherwise I'll only have one chance to get it right.

 

Peel off a little corner of the adhesive backing at one of the ends of the spoiler and set it in place on the window then just peel off the backing and press on the plastic lip of the spoiler. That's how I did mine and it was on there real good and straight too.

 

Thanks Crispy. I'll try it that way. Now I gotta wait till it gets a bit warmer...
