What would the log entry be?

I'm taking apart a Tcraft with the understanding there will be some
rust apparent. My plan is to have the fuselage cleaned, repaired and
primed by my regular IA, with me doing the same to smaller parts i.e.
rudder, stabilizers, ailerons. My regular IA is an hour away; the local
EAA chapter has IAs more convenient.

I know an IA has to make an "OK to cover" entry in the log, but how
does one get the smaller parts signed off as they are cleaned up and
ready for covering?

One approach would be to bring EVERYTHING to my IA all at once; Another
would be to bring in pieces at a time.

How can a IA issue an "OK to cover" unless he sees the complete
a/c? - Mike
