Laurent, I use Minwax wipe-on poly, but I’ve heard mixing any name brand regular poly with 50% mineral spirits works just as well.

If you want a glassy finish on open-grained wood, starting with a pore filler is a good idea. I’ve used Behlens water-based with good success. Just follow the directions on the can.

Another way to obtain it is to apply several coats of the poly fairly thickly, then sand back with 320-400 grit, hard enough to actually remove some of the poly. What this does is allow the poly to fill in the grain. If you just keep adding coats without sanding, you will still feel the grain, so the intermediate sanding is crucial. You may find that you have to repeat the coating/sanding process several times until the surface reached the level of smoothness you’re looking for.
