Hi! Glad you liked what you saw, thanks!
Firstly, I'd say don't paint anything you value, just because it might go wrong! Secondly, with a guitar, it's a good idea
not to paint the fretboard, as it effects the ease of sliding your fingers up and down; neither Johnny nor Chris have painted fretboards. Thirdly, I use acrylics, and I believe Coldplay do too. Acrylic varnish you can find online quite cheaply.
As for how I paint, I just paint a section in one colour, wait for it to dry, then do the next. Mix it together if I want that effect, simple enough. If you want any clear images, then paint the whole thing, then print a stencil, then paint through the stencil!
Anything else, just let me know and I'll answer
