Using a turned-180deg 63 Mercury Vomit roof section, I made up a new roof section, like hundreds of guys have done.

Using the O/A torch I tack and skip around to tighten up the fit.

I use the weld tension to draw up the fits, and gradually work into the corners, as usual like "everybody" does.

Any given section of weld looks like this, about 1/8' to 3/16" wide, 6mm to 8mm.

I hammer the weld, lifting up on the big track dolly as I smack down with a big flat-faced double-face body hammer, stretching out the weld, knocking down the bead, relieving tension, leveling distortion, and improving the strength of the weld-softened HAZ. (heat-affected zone)

I check file it, slapper the low spots, check file, slapper some more, and one more pass with the 12T Vixen gets it to look like this. Standard stuff for 1930's metal men.

okay, go get the ProPail.

I've seen 60 lbs of lead in one panel. There was a name for cars that received that sort of work ....

Kent, were you fusion welding it, or using filler rod, or a combination of both?

Glad to help guys.

Chris,
I fusion welded and added some filler too because I wanted a flat solid bead.

Will,
Show it around if it helps.
Here are two more showing eyebrow method and rain rail end.

Did you let the weld cool complete or did you hammer it hot or warm or cold?

Both.
For thicker weld beads I prefer hot working them.
For thin beads I work them cold.
