Pitted roof from rust under vinyl top repair

Thanks guys for all your advice, I’m setting this car up to drag race with very little street driving and use. Will be garage kept and it will live in Lake Havasu city AZ. With that I’m going to do my best to kill off the rust and use converter, then epoxy primer inside and out on the roof then use a good filler. I’ll be back at it on Friday so I’ll keep you posted posted on my progress. Happy Thanksgiving everybody
