Zinc... And the scrap mental thing was always a crackhead hustle unless your in a contractor based field ie. construction or carpentry or charging to pick up scraps.
crackheads are a.ssociated with scrapping because its quick off the books money, but its far from a crackhead hustle, anybody with a little ambition, knowledge and proper transportation can make a good living off this
i kno everybody on bx aint a college grad or something making 6 figs a year, for those who struggle to make the living they want its nice to bring home $100 to $200 + cash a day for an hour or 2 of total work.
i discovered this hustle 2 years ago when my boy's grandma passed away and his mom paid us to clean out the house, since the new owners were going to gut it anyway we said fu*k that and took everything from the radiators, stoves, and proper copper and brass pipe cuttting, just the 2 of us in 2 weeks total for an hour an change a day cleared $3000, and thats not even counting what we found in the house my mans grandma was a packrat i cant even tell u all the sh*t we found thats another story
