weldable metal paint?

Friends, especially Eesakiwi, many thanks for your responses, I have just found them. Eesakiwi, a question for you:

Here, by Zinc-coated, I guess you mean zinc-plated or zinc-dipped, right? Or do you mean so-called zinc-rich paint? That is supposed to be 90% zinc on application, but I don't belive zinc paint is weldable?

In the case of STEEL-IT, it says the paint is 50% stainless steel on drying. I assume the other 50% is all that organic stuff (polyurethane), which is what I assume burns away when you weld on it, which the steel just hangs on. Am I right?



Thanks agains!
