Good finish for rough sanded 3D CNC piece

[bradleyheathhays]

I'm doing test runs on sections of this really high relief CNC piece I'm working up to carving, and it appears that I'm gonna have a fair amount of fuzzies to deal with after the whole thing is done. Here's the first test...



I've been able to make small sanding sticks using 320 grit that get fairly deep. So even though I should be able to get to the deepest of fuzzies, I'm left wondering about what kind of surface I'm leaving when it comes to applying finish. The top of the structures you see in the pic are relatively smooth, so I'm guessing they'll take finish normally. This is walnut, btw.

Any suggestion for a finish that will get all parts to a uniform color, despite the potential rough spots deeper in the crevices?

Looks cool. Not sure about finishes for that but I would think something it could be dipped in, maybe?

I can't help with finishes, but have you thought of using radial bristle sanding disks, similar to THESE. (The originals are by 3M, not sure how good the knock-offs are in comparison.) You fix 3 or 4 of the same grit on a mandrel and use a Dremel or micromotor tool to spin them. A very light touch gets rid of the fuzzies quickly.

I've used them to clean up after piercing thin walled vases with a dental tech turbine, they are very effective but don't go especially deep.
