My neighbor across the road does roofing. I will check with him. He may be able to get me a lot.
Shoot It would not hurt me to have a few thousand pounds.
Try the wheel weights mixed in. It also allows them to keep the shine. I laughed until I cried at a bait shop a few years back. The Guy that had taken it over, Had a bunch of pure 1 oz sinkers. And a few people would say, I am not buying those old dirty sinkers. They would pick the ones made out of wheel weights as they would shine.. And I told these 2 that the dirty ones would weigh more then the clean one. And when we weighed them. They could not believe when using a pound of them. It almost took a extra 1 oz sinker to make the pound in the wheel weight sinkers.
