Sheet metal repair - fender - correct procedure
Hey guys,
this is my first time doing autobody repair.
Looks like I need to remove the inner structure as well. What would be the correct procedure for that kind of damage?
Would I run into fitting issues if removing the inner structure (and repair it) before making the skin?

The method used by Ron Covey and all the other metalworking experts is to have complete access to both sides of the weld joint so you can both grind down the weld bead and pick the low spots for a proper finish. This does mean removing the inner brace. This is a lot of work to do correctly, and as a result few follow this process. If you are planning to use butt welds for the patch (the preferred method), you will need to remove the brace. Most people use a lap weld with a jog in the patch and the result is both a seam to start rust and a thick section that will telegraph through the paint if you park in the sun.

I patched my fenders with left scrap door skins at work. I butt welded everything and ground the welds down but i never took finish picture of the inside. I replicated exactly what the factory did or atleast tried to .. I patched these up about 2 years ago going on 3 and the fenders where just in primer that whole time. Currently in the middle of repaint and no signs of rust or popping of material. This was also my first time butt welding anything i have gotten much better at it lol.

yes thats my buddys car. came from knoxville to germany 2 years ago. about to complete the engine rebuild in 4 weeks. such a boat!
thanks for your input guys. looks like i'm going to remove the bracket just to save the outer skin.
skin looks good from the inside above the upper edge though the bracket in this area (and beyond) looks like it needs some treatment. i could either cut some more (healthy) skin to reach that area or remove the bracket itself.

An important thing to do, when I do a 2 sided repair, is to make a perfectly shaped and fitting patch for the front part, leaving the rear support in place for reference. When the front is done, trimmed and marked off for reference, putting it back in the exact same location, I then do the back piece. You don't want to wantonly cut both out then lose what the shape and size is. Won't fit when you put it back on!

Make sure to spot the piece in and let it cool between tacks. You do not want to get the sheet metal too hot and create warping/distortion or the dreaded burn through. This job is not really that hard, but does require time and patience.
