Removing a finish

[JB_From_Hell]

I'm in the process of removing all the finish from an Epiphone Les Paul, and wondered if anyone had any suggestions. Last night, I used light grade (150) sand paper to get the neck/back of headstock completely bare, but this obviously won't work for the body. I would like to leave it unpainted, probably tung oiled. Does anyone have any ideas on the easiest way to remove the thick paint from the top? I do not have a garage, so it needs to be stuff I can do in the house. Thanks!
