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,

Yeh, pretty hard to brush gelcoat over Frekote. You can spray your tooling gelcoat if you have the equipment, but the easier solution is to do as Brian suggested. Just make sure the release wax you use is SILICONE FREE.
