I was able to repair mine, and remount it using all pulled rivets. I have some of the big head rivets I bought for belly pan and stuff, but found they worked good on the screen door. I did have to modify the rivets before popping them, as they were "long" I just disassembled them, then ground the "body" down until they were of short enough length to seat inside the door frame, (for those 6) then just a little shorter for the other six, they protrude, but not enough to touch the door frame. I have to admit after scrubbing the door with a scratch pad and all new screens, and remounting with tight rivets, it's very nice. I did not need to bend mine though.. but I think it will depend on if it's the door itself, or the hinges, that are/is bent.
I find on these kind of questions, a picture or two certainly helps..
