foundry fresh alum
Has anyone messed with alum that has just been poured, or say a couple weeks old? this stuff is a special blend (?) they told me and its pretttttty dam hard for alum. the problem im having is outgassing no matter what I do, ( read the tips on outgassing) there almost the size of a pin head,and scattered and never in the same damn place no matter how many times I strip it and start over...
Thanks
