Might best be reposted into the finishing forum, however...
A search will show that Sparky and others use NAPA spraycan lacquer primer, and some others use Dupli-Color lacquer primer from quart cans. Nothing wrong with clear dope and talc, clear dope and corn starch, or clear dope and zinc stearate, either.
Clear dope and rice won't work, nor will clear dope and red beans.
