I think i know what i did wrong looking for some help to fix. I had a big dent in quarter panel that was patched in with bondo from the middle of the wheel well allthe the way up to 2 inches below body line also both bottom so i wanted to keep my curve under rear window. so i cut 2 inches below body to just past the dent then angled to the door abot 4 inches above bottom body line. Any way i didnt feel comfortable but welding the whole thing so i flanged the to and i think my mistake flanged angle to door. All welded in noticed it dipped. In then back out on the. Angled part. Would have to fill with 1/4+ with bondo to straighten back out and the point was to have a clean quarter panel and not a bunc of bondo. Any help would be appreciated

Pics

 

Looks like the problem is hard to photograph. I assume you used a mig welder to do the welding. Let us know.


I think the way you sectioned it was not a problem. Do you think you got it too hot? If the panel warped from heat, I'm not the guy to help you. Maybe someone else could jump in and help here.

 

Can't tell from pictures my guess is not butt welded.

 

Your right i flanged

 

I made the same mistake different car and year.
If I understanding you correctly it looks like this but the length of the seam correct ?

Basically, you need to get a body hammer and dolly and work it straight! if you can't get behind it, I suggest the weld stud and slid hammer the weld stud tool sorry not a pro, I don't know what all the proper terms are. I would ask "coppercutlass" for guidance
Please take better pics so they can give you better advise as I am guessing off of my own example

 

Here's a link to the $99 stud welder that Harbor Freight sells. Works pretty well.
