I've working on 2 Min Dia Rockets. I've had some issues with the epoxy I'm using.... Resin Research 2000CE. I applied a surface coat and reapply it to get a smooth uniform finish layer. After it cured, it looks like a splatter effect of what you would see when mixing oil with water. It would like nice as a paint scheme but, not for a smooth surface. What would cause the epoxy to do this, regardless of brand? Would be because of the undercoat or glass that I used?
