I've learnt all sorts of lessons about customising guitars through often painful experience. I have an original 1989 Ibanez RG550 which I respray every year. For what it's worth, here's my advice.
1. Sand the body right down and don't forget primer.
2. Car spray paint is ace, you can mix it up and have loads of fun.
3. Be VERY, VERY patient. Take a couple of weeks and just spray a bit each day otherwise you can
totally ruin all your good work. I'm terrible at this as I always get a bit too excited when it's almost
finished and end up with a bit of lumpy paint where the stuff has run.
4. Get a solid piece of wood and screw it into the body of the guitar so you can hold it or clamp it while
spraying. You're gonna be gutted if you try to just prop your guitar up while spraying and it topples over.
5. Keep your paint layers as thin as poss. A thick paint finish will dull your sound quite noticeably. You only
need a very slim layer of clear lacquer to seal in your brilliant new paint job.
At the moment my beloved RG Ibanez is purple, but it sounds like shit cos I sprayed it way too thick. I must sand it down again at some point this year!
