Not what you asked for but this is Hondas position on weld-thru. They do recommend it for Squeeze type resistance spot welding but not any other type.
"Weld-through primer should not be used when doing MAG plug, MAG butt, or MIG Brazing. Further study has shown that weld-through primers can negatively affect weld or joint quality."
"When doing MAG plug and butt welding, or MIG brazing, remove only enough of the factory e-coat to allow bare metal in the weld or joint area. Then, apply corrosion-inhibiting primer over the completed weld or joint.”"
