I've never been able to master mig welding.
Even after our body man set mine up for me, and gave me lessons at work on customers cars.
No, i didnt mess'm up!
Guess i dont have the patience.
So i flange weld after properly flanging the edges with just enough overlap so i dont warp the panels.
And dont weaken the panel after grinding smooth.
Thats the only reason i havent restored my 67 yet.
Hope'n with enough practice, i can do the 67 right.
