I've just CNC'd a small sign in a dark grey piece of Corian. I color filled with a gold metallic spray paint and sanded with a 320 grit to remove the overspray. Since the darker Corian colors seem to look best with a gloss finish, I wetsanded with 400,600,1000,1500,2000 and finally used a white polishing paste to bring out the gloss. This seemed to take an eternity. Now granted, I'm doing alll this sanding by hand, but those of you who do this on a regular basis, how do you do it? I have an orbital sander, but I not sure it's the best for a wet environment (electric).
Thanks,
Dave
