I polish the edges of my CF after I CA them. I put 2 or 3 good coats of CA on and then let it cure overnight. Next, I start with 1000 grit paper and go to 12000 grit for the final polish. When finished the edges feel like a freshly waxed car (slicker than snot). It looks really good when you take the time to round the edges on the main chassis plate.
