RE:Galvinized metal (zinc coated) Be VERY careful messing with that stuff in an enclosed area.The fumes coming off that zinc are toxic.They can make you so sick you'll wanta die just to feel better. I got my lesson on the subject when I was cutting a snow plow blade fron an oldtime hot water tank, so I'm speaking from experience. I would not want any of you guys to go through what I did for 2 days!! So watch the heat with galvinized.
