Aluminum + Carbon Stripping Question

Ok, so i have a 99 Quintana Roo Borrego.

It's a Aluminum frame With Carbon fiber parts on it (nice bevels for the internal cable routing and a curvey bit behind the headtube between the top and down tubes).

It has some terrable paint chips and it looks like some of the paint my not have bonded well originaly so its slightly flaky (flaking primer color and clear as one peice).

Normaly i would either sandblast or chemicaly strip the frame but the CF peices prevent that (Right?)
Alternitivly i would razor or sand the frame but i am weary of razoring this frame because i dont want to cut the aluminum or CF w/ a steel razor (is this a valid concern?)
The sanding worries me as the chips are deep and paint bond is questionable so i would have to sand to the frame (again is this an issue on CF?)

Please drop me a line if you have any advise even it is just to resign my self to my dusty hand sanding fate.

A better title would have been: Stripping Paint from a Carbon and Aluminum Frame. There is a highly experienced and helpful member that often posts in the frame building and general cycling boards that may have some first hand experience in this issue. It was Dr. D(something). Shouldn't be hard to find - do a search for "painting" and one of his posts should be easy to find.

As far as my suggestion - lots of sanding with a medium grit paper, no heavier than probably a 320 or so on the CF areas. Paint stripper would be difficult to work with even after masking off the CF areas carefully and with some overlap of masking onto the aluminum sections to ensure no stripper worked its way up under the edge.
