Was looking at the polishing HOW TO--and also considering that there are some types of metal you're not supposed to weld because it lets off toxic crap...

How can you tell if someone gives you a piece of scrap sheetmetal?

Isn't galvenized steel like stuff you want to avoid welding?

that's what I'm really worried about, getting some scrap sheetmetal from work, and they have no idea what it is, and neither do I.

Don't want to kill myself in the process of learning.

So, best practices...regardless of whether the metal is painted/rusted or not...grind the weld area and I should be good to go?

Sounds easy enough. Thanks for your time gentlemen. One of these days I'll have some pictures to show for all these newb questions.
