Any tips for achieving a "clean" break line while carbon skinning?

I attempted masking with tape an area I did not want skinned but came to the quick realization that the resin would slightly cover the tape and not allow me to remove it. BAD PLAN !!! All I know to do is to cure my carbon area, blend the nasty edge the best I can then repaint the area next to it. Also would like do a motorcycle windscreen the same way (glass upper and carbon lower) but getting that break line attractive is not currently workable. Please advise, GEARHEAD
