It can pop in and out at will, sometimes after painting/filling.
Had W114 coupe, the roof to rear quarter panel were "leaded in".
I found this after a bare metal strip down.

Tin canning is certainly a pain. Seen some videos on YouTube of folk chasing it around a panel with shrinking without even having it back in shape first. When welding all the shrinking is in the welds, I don't touch anything else it's just stretching the welds back and panel will go back to its original shape. I have a shrinking disc if I do over stretch it. Tin canning around a welded area normally means you haven't finished stretching the weld adjacent to the tin canning area. If I have it back in shape and there's tin canning, that's when I start scratching my head. 😁
