Well, I've had these side skirts for a while now, and besides the screws in the wheel wells, i used some sort of boat silicon to hold them in the door sills. Well either it didnt' work to well, or i didn't let it sit and dry completely before driving it, but the adhesive started to come off and the skirt would just dangle. My question is, besides double sided tape, what is good to use to hold these to the door sills?? I want something that will last that i won't have to deal with anytime soon. thanks

have a window shop use some window urethane. and then stick them back on.

I use a 2 part urethane epoxy from Norton Speed Grip...stuff works miracles. My previous side skirts and rear bumper were held on with it for about 3 years with no left, cracking, etc.
