I post this all of the time and no one seems to listen.

All you need to do to prepare a carbon shaft for fletching is to wipe down the shaft with a clean rag wet with water and let dry.

All you arte doing when you sand a carbon shaft is creating very fine carbon dust that you can not remove 100% even with alcohol.

I have fletched several dozen carbon shafts with blazer vanes and they will stick just fine if you do this. Glues I have used are AAE fast set gel, Quantum, Zap-a-gap, & Bohning platnum.

Do not clean the bottom of the blazer vanes. They are treated with a chemical that helps adhesion.
