I just bought a 1950 mercury which I am super excited about but after doing some thorough examination I realized it has had a ton of things brazed on. The rocker panels being one of them and it concerns me. Is that strong enough? Should I grind all of it off and weld the panels in? The car was primered and blocked 6 years ago but never got paint and I will need to re-prime and do some more body work. Any advice with what I should do? I was told body filler doesn't stick to braze long.
