I went to the welding shop today to get some CO2 Argon stuff and asked about weldable primer in a rattle can and it turns out it has been banned, at least here in Kalifornia. All they had was a GALLON of brushable stuff. What have you all been using? Any chance it's available at Home Depot Racing?
Cheers, Elliot

Its not weldable....

Brush on cold galvanizing is all it is..a zinc coating.
Because of the high zinc content it might be able to hold an electrical charge...I find it just messed up the weld.
I do treat the metal that I will never see again, then spot grind or spot blast the areas that I will weld so its bare steel for welding.

Looks like a little spot grinding in my near future. (IMG:style_emoticons/default/biggrin.gif)
