  • More acetone-vapor polishing experiments

    hackaday.com 02 Mar '13, 7pm

    This is 100% true. I can’t be completely sure that this is what caused the problems (personally, I think the fact that he used polish remover instead of pure acetone is probably the real problem) but I can vouch for the accuracy of this comment. My previous jobs was working for a majo...
