Hey dj,
Sorry about what happened there. It's painful to even look at.
Also, I'm not sure how and with what you wash your car, but that could be directly related since the cold temperatures you are experiencing are pretty ridiculous.
Unfortunately, I, honestly, don't have a solution for your current issue...but, I'm just worried that your other stripe might end up doing the same thing. Isn't that mod a winter mod? I don't know if the vinyl stripe has a curing time or a temperature requirement....
Maybe one of the other folks out there who have had this mod done can provide some assistance.
