Hi Dave I have two colors of colorant in little tubs but this stuff came in an envelope and not much of it. It sure looked like it colored it through and through but the big area is transparent....can't go back and change that!!!!!! I hope I remember what you said next time I do a color!!!!!!!

I mostly use TransTint, which isn’t rated for use in epoxy, and with some epoxies, it lowers the surface tension, which means they flow a lot better (but also leak out through smaller holes). But I have also been using the System 3 metallic tints, which I like a lot for opaque tinting of epoxy.

Have fun experimenting!

May you have the day you deserve!
