i too am impressed with the results you achieved using bondo, pop rivets, and jb weld. a guy i work with has a canoe thats hull has been held together with jb weld for years. your post made me feel better about the rust repair on my 300D between the rear window and the trim piece. good job!

I thought I'd add some pics and info to help answer some questions I've gotten. I didn't take pics of all the steps like bending the metal and pop riveting or mixing and spreading filler, but this should help a little.

In these repairs I needed to cut and shape 4 pieces of sheet metal.

In all cases except the rail, I glued the metal from the inside and used Bondo filler and spot/glaze putty to fill the remaining void and make it smooth and level with the body lines.

2 were in this area. 1 slightly curved using my leg and hands and fit between the inner support and the existing body metal (at the left of the pic). The other was for the hole near the bumper support. That piece was compound and required a hammer and an anvil to shape. The duck tape was used to keep POR-15 from dripping through and allow it to help shape the repair area.

1 flat piece was along the rail where you see pink peaking through:

The 4th flat piece was here at the window hole above the antenna. Oh yeah, as you can see I actually used JB Weld as body filler before finishing it off with the Bondo products. JB Weld is much more durable than body filler and spot/glaze putty:

I also used POR-15 fiber sheets inside the well to help add strength. You can see the sheet metal between the body metal and the support:

And when you're about to re-install the quarter windows, make sure you attach the trim to the rubber seal before you install the window. The lower trim goes in last after the window has been installed.

Good point.

Here is the link to the thread I did on removing and reinstalling the quarter window:
