I fully agree with zbass on this one, I have been using resin to do all of my molds for years now. I do pour a few hundred at a time, not day in and day out. But when i am running low on a color I pour enough to last a while. I have never noticed a smell unless I did not add enough hardener to the mix. Judging by the color of your mold, you surely added too much. with resin there is a fine line between too much and not enough. beleve it or not weather can also play roll in it. One problem I think people are having with resin and smell is, just because the resin is in a ridgid state does not meen it is fully cured. Sure you can pour it after 20-30 minutes, but it is not fully cured for a few days. So people if you are having a problem with your resin molds worping or getting smell transfer take my advice into cosideration. Make your molds and let them cure for a few days... Yes I have a problem with it also:drool:
