This stuff is so thin I didn't realize I was picking up two at a time when I bought it. The old stuff has more ridges |
Just use a propane torch to burn the zinc off, but do it on a windy day, while staying upwind. Just kidding. I know plenty of guys who welded galvanized steel and have gotten mighty sick (and/or died) from metal fume poising. Or just keep putting vinegar on it, the zinc will eventually go away. The muriatic acid will take the zinc right off, but zinc chloride is also poisonous. If it were mine, I'd just sandblast it and let nature take its course.
