Hood bracing

So my hood bracing has separated from the skin, assume it was part of my accident. I'd really like to keep this hood. Seems like it was an epoxy they used to secure it. Anyone have recommendations for some strong stuff? 

I always thought it was panel bond…similar to what they used on the firewall, floor, inner fenders braces etc.


I could be vastly wrong though.

There are structural adhesives used in the body shop industry that will bond your hood pieces in the center areas quite nicely, and will be mush more effective than the stuff AMC and Chrysler used back when MJs were in production.

 

if you know of a body shop supply store, they would carry this type of stuff.  Otherwise, some internet searching is you next best bet.

Oreillys carries all the 3m panel bond adhesives around here. What they don’t have in stock they can get in a day or two. I don’t think panel bonding to the frame structure in the center is called for here though. I’m guessing there is some reason why they used a pillar foam in place of an adhesive. It would have been easier just to tack weld it in a few spots. Wonder if maybe heat transfer or crash crumpling zones are part of the equation :dunno:

Any welding in the middle of the hood to attach the under structure to the hood skin is going to distort the surface at least minorly, and that would necessitate some secondary work to remove that distortion.

 

Adhesives of any kind will keep the surface skin from “oil canning” against the underlying ribs and making noise.

Agreed. It’s probably similar to the method used on the tailgate panels. On all the hoods I’ve seen, there is a decent gap between the inner frame and the skin in some areas. Panel bond adhesives could not take up such large gaps.
