At the bottom right corner of my bumper a peice of the bumper looks warped and waves up a little. What would be the best adhesive to put in between to try to make it flat. A body shop said stick a peice of would in there because if I just try to glue the part of the bumper to the other half it will just pull it up with it. Or if anyone has any other ideas let me know.

Hmm, I've never seen that happen to our bumpers. If it were mine, I'd probably stick a piece of aluminum or whatever in between there and rivot the top of the bumper down; should look pretty clean after you're done.

That's all I can think of, sorry.

Maybe try heating the bumper up and pushing it back down into place. Don't know if that would screw up the paint though.

you can use either a silicone based compound or fiberglass resin inbetween the bumper pieces

What would be the best silicone adhesive to use?

hell had that problem with mine and i just drilled the hell out of it with wood screws...nice and smooth!
