The ailerons design on the two seat RV's, if built per plans, does not result in an aileron that is 100% statically balanced. There is a lot of service history that indicates that that is not a problem. Even with the wide variation in balance caused by the different paint finishes that have been applied over the years.
Even with that being true, my recommendation would be to add balance weight to an aileron that has been modified from the standard plans configuration, to bring it back to an equivalent level of balance that an unmodified one has (I.E., make it the same as the one on the opposite wing).
The best way to do this would be to add the weight inside the balance pipe. That is the farthest fwd location possible, so it will allow for adding the least amount of additional weight possible.
If it were me, I would use a runny flox mixture with small sized shot. This should reliably stay together. Once added to the pipe, the pipe could be plugged and the aileron stood on end so that the mixture migrates to fill the entire I.D. of the pipe.
