what is the best rod for welding auto bodysheet metal?

well that is the question. Or would a mig flux core be better

.023 gauge wire with a mig welder and gas. The flux core will leave residue that may affect the paint...

Also, flux core wire creates a much hotter arc and the flux sprays off the end of the wire. This results in a much higher likely hood that you will blow holes in the metal.

Ditto nuff, said-----oorrr-- if you want to get all tech.ey you can break bad with a Tig welder and small 70 series wire. mig is 70 series also.
