So adding acetone in my case will result in a mess of "melted" polystyrene sticking to all the edges if you dont properly pour it out, had to use quit a lot of acetone to get it clean. The epoxy went back to a tacky stage as well due to the use of acetone, then came back to a non sticky feel. To be honest I could say its worth the try, experiment with it, but this is not the best way of making part in my opinion Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com

Epoxy is thermoset resin, does not reach with chemicals (acetone, thinner etc.) Your epoxy went back to tacky because, it was not fully cured. Room temperature curing is not good, i prefer always the highest temperature (80-90 C) which i can reach. For example; i heard that big yacht hulls fully cured in one year. Here is my composite works
