Hey guy, I have a revo too and was interested in the same thing before I bought mine. I called up to Predator and asked about this very thing and they let me know you shouldn't use any powder at all on the Revo. Just thought I would share so you don't mess anything up. I know I would be upset if mine got messed up.
If you look on their website it reads:
REVO SHAFT FINISH MAINTENANCE. REVO carbon composite shafts should never be sanded or modified. Sanding the surface of the REVO shaft will damage the exterior finish and weaken the shaft’s structural integrity and release potentially harmful materials that could affect your health. Any sanding, polishing, or treatment of the surface of the shaft with chemicals or abrasives of any kind will void the shaft’s limited-lifetime warranty and negatively affect the shaft’s longevity and performance. Never use talcum powder, baby powder, hand chalk, or other shaft treatments on a REVO carbon fiber composite shaft.
