Yeah, that's true.  As a matter of fact, very little bonds really well to 
carbon, and even less to Kevlar, but you can do better with some of the good 
epoxies out there.  You should call up some of the composite shops, and 
ask if they will sell you their old out-of-date carbon prepreg.  Since it 
is out-of-date (Like medicine that's past its 'best before' date) they 
can't use it on aerospace stuff, so its worth goes way down.  Small parts 
can often be fabbed with cutoffs from the big boys too, so its worth 
talking to them.
