Metal Bonding
Does anyone have any experience in using the "metal bonding" resins or 'glues' for minor sheet metal repair? I read about how it is possible to do, but can't seem to find any first hand experience of its use.
I've got a section on a fender that looks like it will be about 2.5 x 4 inches after the rust is cut out, and have been thinking about bonding a patch into place instead of welding..
Any suggestions or insight is appreciated!

I have used it on our aluminum race car bodies, and it works really well. I saw a rep do a demo at my buddies frame shop, where he bonded 2 pieces of sheet metal together and put it between the chains on the frame machine. Ripped the sheet metal and didnt touch the bonded area.
I would think it would work good for you, plus no worry of warpping the metal trying to weld the patch on. Just prep the areas reall good.

I used the 3M structrual adhiesive setup on my roof and it's working great. It's a two part system simular to epoxy and I tested some spare metal with it and it was VERY strong.
I used 2 part epoxy primer over the bare metal because I was concerned about moisture. I'd suggest you do the same for extra protection or paint over the areas on the back side.

i have used a structural adhesive called duramix. the type of it i used was a medium strength panel bonder. worked very well but remember you will have to either clamp the patch in place or drill for tiny screws to hold it just right. later the screws can be removed or ground off. it worked great. much quicker than welding with no blow thru's or warping.

I have used both glues posted here. I am using the Duramix only now. Manitoba public insurance corporation did a study on the glue vs welding option. They found that the glue does indeed pass all standards in areas of strength. However, they concluded that structural parts still need to be attached using a MIG welding system. Structural would include parts such as pillars and door posts. A roof is not structural and therefore may be glued in place. The insurance companies of course liked this instead of welding because it saves time and that means money.
It should be noted that Duramix requires a special filler to be applied over lap joints, for example where a quarter panel joins a B or C pillar.
