and I see that there is still a lot of bad info here. One thing that you might want to be aware of is that I went to 3 different home centers and mass merchandisers looking for Minwax Sanding Sealer. No one had any. I have heard that this might be going to be phased out of their line to be replaced totally by the Conditioner. But I don't know the creditability of the source.
Or you can make yourown or better alternatives, in my opinion. The DIY sanding sealer that I made up worked great. You do use talcum powder as a filler but that doesn't work either, according to what I have read here. LOL
