Hey Everyone: Anyone know how you can identify zinc wheel weights. I just got about 3 more 5 gal pails from a tire shop and I know that they are starting to use some zinc tire weights. Seems I read somewhere about when you melt them down the zinc will float with the clips unless you get it too hot and melt them in. I melt about 50 lbs or more at a time. Any help will be greatly appreciated. Thanks. Peter aka pistolfan
