    The only alternatives to full skin replacement have their drawbacks. If you weld patches in, there are no feature lines to strengthen that long panel. You could flange the roof and plug weld a patch and use heat gel (works very well) but you're still running the risk of warpage and oilcanning. You could also use a metal bonding adhesive like 3M 8115 but then you could get "ghosting" which shows the outline of the patch when it gets hot. Pretty good chance of that since it is a roof and is a horizontal panel. I'll jump on the "replace it" bandwagon on this one.

    Well I was happy earlier thinking some patches would do the trick but now I don't know what to do. I know a whole roof skin is a big job and really don't want to do that but also dont want to go easy/cheap and it come back to haunt me!

    Patch to start. Don't get caught up with a lot of spot welds at a time or you will make a mess.
    If you soda can the roof its game over. If you lay a bead of weld its game over.

    If the patch doesn't work for you after you try then skin it.

    Try the panel glue. Flange the edges and your your set. No distortion from welding and it's not in a critical structural piece.

    of course the professional body guys say replace the whole skin

    the DIY guys say just patch the holes

    weld some patch panels in & skim with some good mud...it'll be fine

    I used a damp towel to keep the roof cool on a Ford F150 I was working on.Went really slow,one spot wled at a time.It turned out fine,And yeah I know there are products to do the same thing as a damp towel,but I'm cheap.If you could flange the hole,would that stiffen the metal to keep it from oil canning?Or maybe warp it right off?

    OR.......vinyl roof?

    New roof is easy. Better than skin.

    Or
    Leave it and cover with a hatch.then you will have sunroof and ejection seat opening

    Probably will try to patch first, if it fails then I guess I'll have no choice but to replace the whole skin. Thanks for all the replies guys

    I've done a full roof skin replacement.
    But this, this I would absolutely patch.
    1 tack at a time. Let it all cool down, tack again, let cool, etc. No rush on that.
    And honestly, that's such a small piece, I'd barely worry with curvature.

    You've got nothing to lose doing the patches. If they don't work, all you've lost is time. Slow and steady wins the race!
