The problem with doing it that way, Dennis, is that you're only filling the small gaps between the infill piece and the original panel. As the metal expands and contracts there is not enough filler in that small gap to cope with the size changes, so it cracks.
Doing it Jay's way means you have a larger piece if filler in there which is less likely (not guaranteed) to crack around the edges. I've done a couple like this, at owner's request, and they've held up really well; one on a Nissan Patrol that went thousands of kilometres through the centre of Australia, over corrugated roads in in crazy high temperatures. When he came back, some 9 months later it looked just like it did when I did it.
The trick is to use really high quality panel adhesive and make sure it's on well cleaned surfaces.

To each his own, I did a similar deal on my Plymouth rocker panel years ago and displayed it here on the board, you may remember it?
It still looks good to this day BUT I did clean the adhesive out of the gap then beveled the edges slightly then filled beveled gap with Fiberglass filler I did include that in my post, still a lot of experienced body guys frowned at my repair. Ditto on using Hi quality Panel adhesives Not all are really good. When they are used correctly they are a good alternative to welding for some repairs in my opinion. Dennis B.

Dennis, sure its not the ideal fix, but its about all you can do when you don't have a welder and know how to use it on sheet metal. the shrinking edge is the problem. Jay D. they say my name is Jay

I went with some copper pipe I had, cut it lengthwise then flattened and fit pieces into the holes with jb weld between and this getup holding it for a day:
Seems to have held up nicely amid all the sanding that took place afterward: |
Yup, that'll do it...........................not.
...and now you have two. Might be fun to run a book on how long this lasts and whether the paint over JB weld will fail before the compromised paint not removed. Chris
