Well I have this old ('87 or '88) Ibanez S540 that I would like to repaint. It is in this awful dark metallic purple/red, and the previous owner did NOT take good care of it.

My question is: when repainting a guitar, would one typically sand down to the wood or just down to any primer? There are several large chunks of paint missing so I would likely have to reprime those areas anyway.

Any technique or product suggestions? This is the first time I've done something this stupid to one of my guitars, and I could use any recommendations.

I can also post pics of the guitar if necessary. Or if you guys just want to check it out I can accommodate :P
