A lot of it may not be that noticeable if it's buried deep enough. Especially with the dark walnut base coat.
I just quoted myself there...

I got your projects mixed up! I thought we were talking about the brown hollow body. You've got too many guitars going for me to keep up!

Anyway, my thoughts are the same regarding the fix.
I also agree with Jim C, that once you level & polish, you may be surprised just how much the particles aren't visible without very close inspection. If I judged all my finishes on sighting from 3 inches away, they'd all fail!

As for the rangehood/box fan idea, that concept is flawed unless you're starting in an already perfectly dust-free environment.
The rangehood or fan that's meant to be extracting is more likely just pulling dust in the direction of your project.
