So I got the DP CF side panels and they need a little trim where they meet the frame in the front. Looks like they were designed to work without frame plugs but even when I remove the frame plug it still needs a little trimming. So I bought a Craftsman dremel tool. Now I am wondering which attachment to use, the sanding drum or the silicone carbide grinding stone? New at this so any tips about using this tool and it's use on CF would be appreciated - Thanks in advance for your help.
