Hey guys I'm going to score a bunch of mostly soft lead tomorrow and I'm fully aware i need some tin and or ant. To go with it. So I found someone in my old neighborhood selling Kester 63/37 Tin/Lead Sn63/Pb37 Solder Bar Ingots reclaimed from an electronic soldering machine. They want 6 bucks a pound and I'd like your opinions on cost and if you've ever heard of this stuff. ASAP! Thanks!
