Has anyone had this happen? This is the first time I have used a pigment additive in my epoxy and also the first time using a liquid mold release called Frekote 700nc. I was attempting to apply my first coat of epoxy to my plug as I have done on my first plug with good results. As soon as I started to brush it on, it started to separate. I was able to wipe it off very easly before it cured. However, I am wondering if it could have been the pigment additive.
This is only the second mold that I have done. The first one worked fine other than my plug construction, and plug surface quality was poor. So, this time, I did a lot research on construction techniques and proper plug surface requirements. After reading about different mold release types, I choose to use a liquid type. From what I have read, you can achieve a better molded part surface finish.
Any input would be great.
Thanks,
Lee Adams

Sorry for the late response everyone...
Brian,
Thanks for the quick reply... You saved my weekend!
I did just as you said and applied the wax after the frekote, and it worked but I had to keep spreading the epoxy until it started to thicken, because if was still fish-eyeing in a few spots.
Hanaldo,
I checked my mold release wax and it was silicone free, there is so much to learn! Thanks!!!
f1rob,
I checked into chemlease but it was not available locally.
Warren,
Fish-eyeing is not very cool, but I guess this is how you learn.
Thanks!!
Thanks EVERYONE!!
