You can use fletch lac for carbons. The gasket will not work, fletch lac must be dripped. You should also dip it in clear first to help it adhere. The issue you will have to work out is the paint pools at the end of the shaft and leaves a bump if you just plug the hole and dip it. You need to make a taper for the paint to continue travelling. A golf tee works pretty well for this and works better if you whittle the tee to a better fit. Bohning also makes a dipping plug that is made just for it.
