Thanks for the tip, my appointment is tomorrow. I'll try and see if I can convince them to just sand the area, then try to use that epoxy you mentioned. I bet they rushed the install, and didnt give it time to properly cure. Also its been averaging -10c up here, so when I remote start the rear defrost turns on automatically. I have a feeling that because it didnt cure properly, combine with the fact they warmed my JL, before I picked her up. It screwed up the process, and the bond weak.Be sure to mention conductive epoxy.
best of luck!
