Is it true that recent manufacture of lead wheel weights have a much higher concentration of lead than those manufactured say ten years ago? Up to bout 98 percent now?
Doc, as I understand it, it is now a much LOWER percentage of lead. Some say the wheel weights are mostly antimony now.
Wish they were. Then we could melt a high heat and skim the alloy off the top leaving (almost) pure lead. But, sadly, not to be.
