If free, wheel weights are great. If you have to pay lead prices, then not so worthwhile. I just bough some more pure lead ingots for 35 cents a pound. He had a LOTS more, but shy on bucks. No need to wast the time and effort with the mess of wheel weights.

The worst of it nowadays is that many of the zinc clips are not marked as zinc. If even one gets into your lead, good luck with your casting! You have to be extremely diligent to test each WW for softness so you don't let a zinc one slip past. I scratch mine on the pavement. The zinc is harder. A real problem and PITA.
