Foxer Posted December 7, 2010 Posted December 7, 2010 I have some really old resin and molding putty kit from Micro Mark that I know is too old from all I've heard. I must have gotten it 10 years ago, but I never throw anything out! I know the resin is way past it's shelf life, but I am wondering what actually happens when it is "too old"? Does it just not set up? The RTV silicone putty may be a different story and I'm going to try to pull a simple mold using it. Got nothing to lose and I'll know for sure to throw it out!
MicroNitro Posted December 7, 2010 Posted December 7, 2010 The resin will absorb moisture and get lumpy as for the RTV it also will absorb moister witch will then go off quicker. I hope this helps.
Foxer Posted December 7, 2010 Author Posted December 7, 2010 Thanks Jim. I did try the molding putty and it seemed to work fine. I just did a squish cast against a body to get a door handle impression.
