Fishnmike Posted June 15, 2012 Report Share Posted June 15, 2012 Posted this in the tool forum but didn't get any responses so thought I would try here. After a lot of study here I made a Bondo mold for a large pyramid sinker. Before I use it was just wondering if there is any prep to do to it to aide in the relase of the sinker after it is poured. Thanks, Mike Quote Link to comment Share on other sites More sharing options...
dlaery Posted June 15, 2012 Report Share Posted June 15, 2012 I am going to guess that talc powder would be the best. Baby powder might work but I don't know what else is in baby powder. I use talc for silicone spin cast molds. Quote Link to comment Share on other sites More sharing options...
dlaery Posted June 15, 2012 Report Share Posted June 15, 2012 I buy the powder from Tekcast industries. Another place would be Contenti. Both have websites. Quote Link to comment Share on other sites More sharing options...

Fishnmike Posted June 20, 2012 Author Report Share Posted June 20, 2012 Thanks Cadman, I'll look for some of that. I don't want to get a 12oz pyramid sinker stuck in my new mold. Quote Link to comment Share on other sites More sharing options...
