Gluing trunk/frunk skins to frame, Need ahesive recommendation Options

[bbrock]

Doing a bit of rehab on my front trunk lid in preparation for paint. One side of the A-frame member is stuck tight to the skin but the other side has lifted off about 3/32". I want to glue the lifted side down but don't know what adhesive would work best. 3M Panel Bonding Adhesive looks like it would be the ultimate but kind of expensive and probably overkill for this application. Any suggestions?

Thanks Jeff and Andrew. I had never heard of anit-flutter foam and that looks pretty ideal, but also cost prohibitive for a one-off application like this.

After refreshing my memory on what Kent did in the link I posted above on Cairo's Six, I decided to follow his lead and clean out the old factory adhesive. Doing that was great because I was able to see exactly where the factory applied adhesive and what they used. The stuff I pulled out is clearly a butyl caulk, still tacky and stretchy in the parts where the frame hadn't separated. I ran a test with scrap metal and verified that cured 3M weatherstrip adhesive is pretty much identical in look, tackiness, and stretch. The foam would probably be the superior product to use, but the weatherstrip adhesive will be more economical and will very closely replicate the original factory treatment.

Below is an updated image showing where the original adhesive was applied. Same as what Kent did but figured I'd post here in case someone stumbles on this in the future. The caulk was applied to the inner flange of the frame member only. (IMG:style_emoticons/default/beerchug.gif)
