Is it necessary to have clear coats on the guitar if you want to buff it etc.? I am currently painting my guitar body with a nitrocellulose olympic white (Cellulose will yellow over time) and I have heard that without clearcoats the yellowing won't be that critical as with clearcoats. Hence why I am wondering if it's necessary to have clearcoats if you want to wetsand and buff.
The shine of a guitar's finish is from the clear coats, and it's purpose is to provide protection of the color. If you're wanting to avoid the clearcoat yellowing, don't use Nitro. :)
