I feel it would be irresponsible of me to not clarify the process of painting the guitar body. While many, much more in-depth, tutorials exist on this topic, I should make you aware that I really short changed the process.
My post on painting the guitar body simply jumps from sanding, and not very well, to spray painting the body. I felt I could neglect precision on this step, as I would just be coating the body with aluminum flake anyway. While this may be true (mostly), I should have followed proper procedure.
Similar to sanding a lacquer finish, I first should have sanded the surface multiple times, with sandpaper of increasing fineness. After properly cleaning the guitar body, I should have then applied a few layers of sanding grain filler / primer. You apply this like a traditional primer, and then sand it smooth.
It is at this point, that I would then paint the guitar body with the appropriate paint compound, and proceed with the remaining steps as I had outlined.
Ultimately, this doesn’t matter much in a project like mine, but I thought you should be aware of it if you had decided to forgo the flake, and finish a painted body. Google around, and you will find some good tutorials.
