Polishing brushes and buffs

The white detail abrasive brush, the 280 and 320 grit abrasive buff found in the Dremel polishing kit had the best polishing results.

Polishing speeds

Use the slowest speed on your rotray power tool to polish the surface without damaging base layer.

Polishing techniques

Start with the 280 grit (it's the hardest brush to squeeze.) Use the slowest speeds on the Dremel and begin smoothing out the layers by blending them together. Use a back and forth motion as you polish along the seams. 

Focus on one section at a time, try to blend the layers together and go back over sections to even out the surface.

After smoothing out the ridges from the surface, polish each area a second time to bring out more of a metalic shine.

Switch to the white abrasive brush for the contours and hard-to-reach areas.

Polishing compound

The Dremel polishing kit includes a polishing compound. Apply to the surface using gloves. Rub it into the surface to fill in any holes.

Buff

Use the 320 grit abrasive buff to finish and smooth out the surface. The buff really adds contrasting tones to the overall look of the parts.

Comparision 

Comparing the surfaces of these parts you can really see how well the polished part comes out. Definitely worth the time finishing your copperFill prints. A great alternative to the rotary tumbler.
