    I had to replace a 2 x 3 area in the lower rear of the door, rusted from the inside where the inner panel and outer panel touch. I have also noticed surface rust developing on the "rolled" section of the door, i assume it exists on all three sides.
    Question is, what has anyone used to seep between the roll to stop/prevent further rust, beside replacing the outer panel.

    If there is not any oil in there POR 15 is like water and you could pour that in there or squeeze it in with an eyedropper or small baster.

    Alternatively, Gibbs oil can be sprayed in and it says you can paint over it. It evaporates eventually and leaves a barrier. Fluid film will also seal it but it is lanolin based. Both will need to be reapplied periodically. You could fill it with a paint or as suggested a cavity wax and then apply the gibbs oil to ensure everywhere gets penetrated.

    I think I will try the Gibbs oil and see if it will seep into the seams and the prime and the rust proof

    Gibbs is great stuff but not right for this application, likewise for Rustoleum, POR15 or anything other paint. Cavity waxes are developed specifically for this purpose, used by most modern auto manufacturers and definitely the way to go

    My friend who is a body man says not to fool around with the doors on my car. I have a little surface rust in the corners where it rolls over and he insists I should reskin them. I'll figure that out someday when I get that far!
