Orkestra

I recived this body (with broken neck... i know, I know!) from a friend, the front had most of the paint removed and had been used as a practice pad for a drummer for some time! Needless to say, its in a bit of a state, I began to try and sand it down, but decided to ask for a second opinion; just in case I ended up ****ing it up even more. Im going to spray it white; eventually. Ohh... yeah: How do I get a nice, even surface to spray onto? That was my original question I suppose
