Good write-up...I've done the same in years past but never used the sharpie...I've have to try it next time...

My only difference is I graduate the sanding, starting with 320 to 600 and finally 1000 if needed.

I have a question with regarding to polishing the face of a carbon fiber chassis. I recently purchased a new kit and the carbon fiber face is not polished / shinny? Its dull. Does anyone have any suggestions. Not that it matters as I run the car as is, but thought I'd ask.
