Shaving drip rails

Anyone here shaved the drip rails on a Duster?
We are building a Duster Bb ( 511) bracket car, car has rust damage on drivers side drip rail and a little in roof above windshield line.
I will make patch panels for roof rust but, not sure drip edge ( gutter) is worth saving- i know there is rust between sheets.
Thinking of just shaving them and trying to flush out windows a bit.
This would let me get more rust out of the old girl.

Any pictures, ideas, experience would be greatly appreciated.

Oh btw- Hello to everyone from an old Texas geezer.

Thanks,
Rusty
