Pitted roof from rust under vinyl top repair

As I understand it and going through it on my car, yes treat the rust however if you have pin holes or large areas where the metal is thin, re skin the roof. My car was treated where it was pitted then epoxy primer, then filler etc. has been that way for years I'm getting ready for the last coat of 2K then a sealer and paint so far so good...car has been garage kept since 1993. I believe I used a hand sand blaster then used Rust Mort but evaporust also works its a light acid like vinegar. I also hand sand blasted all welds on the car as wess as welds like to rust.

The guy in the video is "My Friend Pete" he cusses and swears and pisses and moans but he does great body/resto work. He's one guy and he's getting old he isn't fast as lightning but good.
