Best way to separate pinch welds

I rarely allow myself to use an air chisel because i somehow always end up with a slip here or there and making more work for myself lol, but they definitely make some jobs easier i used the drill method on my wheel house removal and the great thing about it is i was able to drill all the way through in a few places so that way i have alignment holes for when i put the inner wheelhouse back in after i finish widening it

I agree with you. I rarely use the air hammer unless im cutting junk metal out of my way. After you either grind or drill the spot weld you dont really need it. Like body person said. Putty knife or even a gasket scraper and a light tap and they pop easy when done right
