Yes it can be done, but the solvents in the dope disolves the zinc
chromate primer.
It's better to use a two part primer that the dope will adhere to, but
not disolve.
i suspect that back in the 70's two part primers were not that popular
so the people who covered aircraft used what had been used all along, ZC.

Please correct me if I'm wrong, but I believe I've seen multiple
fuselages from the mid-70s that were ZC primed and covered in
Ceconite, so I'm thinking the dacron adhesion to ZC couldn't be much
of a problem! Again, please let me know if you think I'm miss-reading
what I've been seeing - Mike

According to the Polyfiber manual, you can prime over the ZC with epoxy
and then the dacron will stick using polytak.
