Hi JMAC, You want to assemble your box first making sure you have cleaned up the glue that has oozed out. The oil will not permiate the wood where the glue has dried. Any good wood glue (titebond, elmers wood glue, ailenes) will do. The beauty of using oil, is that it doesn't matter which way you put it on. Rag in on, dip it, sponge, brush. Oil soaks into the wood and leaves you with a beautiful finish. Drain the oil or wipe it off good and let it dry then spray with a poly finish. Done.
