Looks very flexible - thanks for the pic. I think just the regular resin will do the job. Does heating briefly with hair dryer or heat gun give more flex temporarily?

Epoxies once fully cured are thermoset plastics so cannot be heated and reshaped. They will, however, go soft and distort when initially brough into contact with heat while the parts are fresh.  This is because at room temperature not all the molecules have cured hence the first initial increase in temperature can soften the resin while the final curing takes place. This softening does not mean you can reshape it though as it would distort and the smooth surface finish would likely be lost with "print through" of the carbon fabric onto the surface.
