Any finish that will seal pores?

I'm very pleased with the results I got with a can of Watco Danish Oil on poplar. 3 days after the second application, I gave the work a coat of poly and was surprised at how nice and smooth it turned out.

I'd like to try for a similar finish on red oak (an open grain wood), but to do it, I'll need something that I can rub onto the wood which will fill all those tiny pores before the final app. I'm thinking I could make a thin gel of Danish Oil with Cab-O-Sil... this is a translucent fumed silica of very fine particle size, which becomes nearly transparent when wet, plus it's very inert and won't produce any off colors in the wood. Poly's drying time & characteristics make it unsuitable for use with Cab-O-Sil, but I wonder if Danish Oil might do the job... unless of course there's a commercial mixture I can use instead. Anyone tried this?

Ditto on the Constantines brand. Works better than any other solvent base grain fillers I've tried. Follow directions carefully.

Geeze, I didn't think anyone had access to Cab O Sil, except paint manufacturers!

We used to use that to make flattening agent.

I doubt it will give you the pore filling properties you are looking for. If it does fill a pore, it will probably not be very stable and could crack over time.
