A repair is one thing. Upsetting the mass balance of a control
surface with a repair is a serious offence, and one needs to be careful
about keeping things right.

Perfectly correct.

In counterpoint to Dan's example, Beech does not allow *ANY* repairs on the magnesium
ruddervators on a early Bonanza. After seeing how tight the balance is on those things I
wholeheartedly agree. I would be very leary of an early Bonanza that even had bad paint on its
ruddervators.
