I always double check the balance of all control surfaces after I have
primed the part for the first time (usually 2/3 coats rolled on) but before
I begin sanding. The weight of all that unsanded primer is as close as you
will get to the ultimate finished weight. At this point, with static wicks,
trim tabs, cotter pins, etc. an elevator should be 1" or so overbalanced.

I'll check again just before the part is painted and confirm that it is
still slightly (3/4" or so) overbalanced. It is easier to remove lead than
add it, but this method is quite accurate and sometimes I don't have to add
or remove any. Of course the amount and type of paint (base/clear or single
stage? Sealer?) will have an effect as well.
