Thanks Katherine,
Will this work for a thick layer to cover the bottle caps and have a smooth surface? If not, maybe I can just use it to anchor them in. But, ultimately I would like to cover completely and have a smooth surface so it can be used as a serving tray. Would it maybe work if I do it in layers and let them cure in between? Ive never worked with any kind of resin before. I think Ill try out the coasters first.
