ArtResin epoxy resin has the viscosity of honey, so you can brush it on with a disposable foam brush. Repeat until everything is covered to your desired thickness. You may need to work in layers. If you are resining a cube, you can work in stages by coating one face of the cube at a time (i.e. resining the top flat panel of the cube, waiting for it to cure, then flipping the cube around so that a new face becomes the top flat panel, ready to be resined).
