Old Tyme Body Work

As a professional welder for 25 + years and having restored my share of MoPars....
Brazing will get the job done, with that said I personally would not finish the car with it because of the above results are true.

go find or borrow a small mig welder and finish the job. I’m assuming you were running e70s with 75/25 or straight carbon dioxide. There is a lot of truth to the “old ways.” Of doing stuff.... there is a real reason it’s “the old ways.”
And how dare you not share some pics! Lol!
