Flexible Adhesive

I am looking for flexible adhesive that I could use to hold an oil bath air filter inside the grill shell of a tractor. The air filter is held on at two sides of the grill. One side is an internal cross-member that can be bolted. The other side is the outer skin that is already painted. Normally the brackets for the air cleaner would be spot welded, but I'm hoping to glue that half that goes on this outer panel. This is a large oil bath air cleaner - maybe 5-10 lbs. I do have plenty of surface area to glue the bracket (about 24 square inches). My main concern is vibration. As big as that air cleaner is in relation to the bracket makes it a pretty big vibrating lever. Also, the fit isn't going to be perfect from the bracket to the outer skin, so gap filling ability would be a big plus. If I try something and it fails, the other side that is bolted will be enough to keep anything too bad from happening. I'm open for creative suggestions!
 
Any two part panel bond product would work.They are not flexible and you don't want flexible. Especially for what you described.

Something like this:

Not sure but would 3M 4274 Duramix NVH work? It is what I used to seal the gaps between my hood skin and structural supports.
Remains somewhat flexible but I am not sure of the structure strength when cured.

It doesn't have any structural strength. It is a dampening foam.
Maybe I misunderstood the question though. I thought he wanted to bond two pieces together in place of the spot welds.

Do you mean the the air cleaner will be offset on a bracket?

FYI, all the panel adhesive that I'm aware of is for bare metal, not painted surfaces.
So to use panel adhesive, the paint will have to be stripped.
If that is the case, is spot welding then an option?
 
Yes, the goal is to bond the air cleaner bracket to the side of the grill shell. I will sand the epoxy off the inside of the grill shell where the bracket goes on, if needed. However, I don't really want to refinish the outer (visible) part of the grill shell, which limits me to gluing vs welding.

I have never used any of the panel bond adhesives. Is there anything with good gap filling abilities?

Yes it will fill gaps within reason.
 
Keep in mind that shear strength is panel bonds weakness, and it sounds like that will be the pressure you are putting on it, with a "hammer like" force.
