I think I know the answer, but figured I'd ask here before reluctantly removing the vinyl.

I have a little rust stain showing on near the drip rail/edge about 2 or so inches above the windshield on the 77 Gran Fury.
Is there any product that can possibly slow the rusting, this isn't a show car, its an original daily driver that is in decent condition, but will never be restored. I intend to just drive it and enjoy it.

I'd rather not remove the top, because it's in overall good shape. But if the roofs going to be rotting away and leaking then it's gotta go.

I didn't know if there was some magical sealer I could use on the vinyl to extend it's time.
