Fathand is right. French polish doesn't lend itself to shortcuts.
When I learned to french polish I was taught to pore fill with the same pumice and shellac method described by redir in post #3.
I like a 50/50 blend of FFFF and FFF pumice and a larger fad (golf ball size) with coarser cover (cotton terry cloth) for the pore filling. I tint the pumice a little with black or brown dry pigment to make sure the pores stay at least as dark as the wood.
I've tried other methods, but always end up coming back to pumice. I'm going to spend 20+ hours on the FP finish, so I'm not going to risk it by trying to save an hour on the pore fill.
