I am no longer set up for casting and have some left-over materials that I would like to sell. But due to their weight, better if you are local, I live in Lake Country, British Columbia, Canada.
I have:
around 50lb or so of Petrobond.
around 5lb of parting powder.
Some zinc ingots (will weigh later) possibly 15-20 lbs
Some za12 ingots (will weigh later) possibly 80-100 lbs

If there is some interest I will weigh all the stuff properly, let me know.
