Carbon Fiber Question

[bkathsalero]

So here's my dilema. I'm doing the carbon fiber GA front end swap as many are aware. The kit will only match the aed alero rear kit. And I'm having a hell of a time getting the rear bumper. So after comparing the alero bumper to the ga bumper I see that the only difference is the trunk lip. Meaning I could buy a Ga rear bumper (CF) and cut the trunk lip to fit the alero. My question is does anyone know if you cn cut carbon fiber and keep a clean look? I'm guessing not. So I migt be stuck with buying the matching kit in non-CF. That way I can cut and mud it to look good. Any ideas?
