Thread: Another epoxy question

Despite my efforts to attain that flawless finish from poured epoxy, I still can't seem to be able to do it (I always need to sand out some imperfections). I used to have problems with flecks of dust and such getting trapped in the finish, but I managed to solve that buy having the epoxy cure in a relatively air tight container. My biggest problem now is that I'm ending up with (for lack of a better term) voids in the finish.

I'll thoroughly coat the scales in epoxy, making absolutely sure I don't miss a spot, then set them aside to cure. But after the epoxy has set, I always seem to end up with little voids in the finish, usually no more than a few sq millimetres. It can't be a problem with lack of epoxy, because I always have to deal with drips of excess forming on the undersides of the scales as well. And I spend several minutes mixing the epoxy before I pour it, so I doubt that's it either. My best guess is it's caused because I usually shape my scales to be smoothly curved down the edge. Being as such, the epoxy gets pulled down towards the edges (and then drips off) and epoxy on the top part of the scales thins out so much that it's surface tension pulls it apart to cause the voids.

Anyway, if anyone knows a solution, I'd be very appriciative to have it.

Here's a few pix to show you what I mean.
