What glue should I use to glue crystals on my brush?
I have tried a couple of glues, and the one that holds up over time and through the acrylic liquid the best is an epoxy-type glue, a two-part glue that you mix together (one is a resin and the other is a hardener). I like one that’s called Great Planes Pro Epoxy 6-Minute Formula. You can purchase it at hobby and craft stores.
