I knocked down the imperfections with a belt sander then finished with a 6" orbital.
A couple of months later I ran across a video where they used an Amana CNC spoilboard bit, something like a RC-2257. It has a 2-1/2" diameter. Amana does not recommend that bit for a router but this guy had a pretty good extrusion rail setup that gave him complete control of the router travel.
