Ok, I did a 15.4" flip down in a excursion over the weekend. Well I had to cut the crap out of the headliner. Well where it went in one of the main air ducts for the A/C. Well now the overhead is getting water in it from the air. What in the hell do you think I could use to seal it back off as much as possible? I thought about tape, but I think that will come right off. The hole is about a 6" by 4" probably. I needed to get the mounting braces up there. Any help would be great.
