Been oiling up some shelves and started building with a little oil/thinner/poly mix. Started wet sanding with 400 then 600 and wonder what the correct method is. I've been wet sanding lightly and then wiping off the finish to get any grit removed and then wiping on a new thin coat. I'm not trying to pore fill or anything, just want to build a little poly to get the "wet" oiled look. Is this correct or do I just wet sand and let it set without wiping off?
