Bondo is not a good material for molds.If it gets too hot it will crack.
Try making em as big as u can so the heat dissipates better.
Tin is 2/3 the weight of lead.U can find in in metal scrap yards.The stuff we get was used as beer coil..They will cut it with crimps be sure to open them up as they will contain moisture.NG...
Scratch a few lines in the flat part of the mold to help the air escape this will help the metal to flow into the mold better..
Looks good just let em cool an u will be fine..
