    My 70 has a few minor rust bubbles in the very edge of the panel Near where the metal folds over to secure the skin to the Trunk inner frame. Other than that it is perfect. Guessing it’s moisture caught between the skin and trunk frame. What is the proper way to repair this permanently?

    Sand down to good metal.
    Cut out bad rust, Patch.
    Primer it for paint

    This is the right way, but depending on where it is, might be difficult. You can also sand it down and metal filler over the pits. This is why I want a pristine trunk lid.

    When that area gets fixed soak that trunk panel with rustproofing or WD-40.

    Depends a lot on what you want, and where you take it. The shop that my car was in, the guys might tell you to get a new lid if it had spots like that. Faster, better and cheaper because what you see now can be a whole lot different when you start sanding
    Labor hours add up frigging quick as hell on rust repairs. That's something the " Cut out, Patch, Fill, Sand, Primer guys " aren't telling you
    Thats moisture from the inside, and that's where you find all kinds of nice e surprises when the work starts .
    Ask me how......

    Definately need to be ground down to bare metal and cut out the area so you can see if the issue is confined to just that area. The inside needs to be blasted and treated to stop the rust. If the rust runs the whole length of the trunk but hasn't busted through it will cause problems you don't want to deal with after you've paid $$$ for a paint job. If the lip on the inside shows no sign of issues you might be able to just repair that area.

    I ended up buying a new trunk lid in ‘85 from GM when my car was done. Would have had too much time wasted on it.
