Having done some research I see that not all resins are good to use for table/bar/desk use due to the possibility of scratching the surface. Before people suggest normal paint, I've had plenty of bad experiences with this and rubber feet of equipment stood on painted surfaces for prolonged periods of time. Additionally I'd like to have more 'depth' in the colour/design of the desk. That said I'm not planning to embed coins or other objects in the resin.
