I have customising aspirations to have a painted roof and don't think that there is any rust, but will be yanking the ratty top off. I am planning to then cover whatever is there with body filler and smooth it, then paint the top instead of redoing in vynyl.
Any reason that this is a bad idea as far as smoothing over what's there and making it all look like it's one sheet of steel/smooth from a cosmetic standpoint? I like the smaller rear window and want to keep it.
