So I'm about to paint my guitar. I have Duplicolor sandable primer(black), Black Lacquer paint, and a clear gloss. What are the preparations I need to take before painting it. Also How do I go about painting it? Any help would be appreciated!
How is the guitar currently? Bare wood? Grain-filled? Or already painted?

"Show me war; show me pestilence; show me the blood-red hands of retribution..."
There is some paint that is already on there that I have to to remove. The paint is only on the back though. Other than that it's bare wood.
