I have an old ibanez edb600 bass, which has a luthite body, that I about to refinish. I started sanding the body, based on but am curious, how far down should I sand? I'm not sure where the clear coat ends and the luthite body starts. Here are some photos of what I have so far

My main concern is in that second photo, I can't tell if the white layer is the luthite or some core layer that shouldn't be sanded. Any tips?
