      This question comes from Ron:

      Is it possible to thin the mixed resin so I can use it for a final finish? I don’t need to put a thick coat for the final finish. I just want to make the piece have a glass finish.

      Hi Ron,

      In a short answer, yes, you can do this. Solvents like acetone and alcohol will thin resin once it’s mixed. Be sure to add no more than 1 part solvent to 10 parts mixed resin as it may inhibit curing. The problem with doing this though, is that the thinner you make the resin, the less likely it wants to stay on the surface of something. Think about the consistency of honey as it compares to vinegar. Honey is thicker and will coat something well, whereas the vinegar is thin consistency and won’t want to stay on the surface of something. If your surface is flat, you can likely get away with thinning the resin and having it stay on the surface, but if your surface has any curve to it, thinning will allow the resin to pull off and leave voids.
