Have a BIG question. I have been asked several times to airbrush guitars. Matter of fact, I have one here now that I have to paint (The guy wants it as a wall piece). My problem is this, Im using water based paint, and as we all know, require clear coat. My guitar guru son informed me, that I cannot use my normal clear coat on the guitar, because it will distort the sound. I know some of you have airbrushed guitars, what kind of a clear coat did you use?
