Filling in panels with foam...

Has anybody ever done this??? I was thinking of spraying some of this foam in my back wall of my truck to keep it from flexing so much. I would be using this...

That shit expands LIKE CRAZY. I believe it expands to 10x it's original size...I used it to fill in some of the panels in my old car's trunk. Works pretty good just make sure you don't spray it on anything you need, lol. It will fill all gaps and hardens pretty good. I think you can cut it with a knife when done however.

I haven't used expanding foam in years. I always got good results with it, but it's messy as hell to work with...

meh, just go to walmart and buy the regular expanding foam...just be careful with it. Don't spray a ton in at the same time. Spray a little in the bottom and let it go for an hour or so then come back and spray some more...until you have it filled!

If you have metal flexing, I don't think expanding foam will help much.

Why not? Adding mass to a panel is exactly what you do to keep it from flexing...

I figured it would create some force between those panels and stiffen them up abit.

But foam isnt going to add jack for mass.
