I'm in the final stages of finishing an oak poker table. I have applied 3 coats of deep mahogany oil, which went on OK but didn't really soak in well after the first coat.
Now I am applying 3-5 coats of polyurethane. After applying the first coat I felt small bumps here and there and so lightly sanded the surface with 400 grit paper. I have a smooth surface ready for the second coat now but I'm left with what looks like poly smudge marks in two places, possibly from pressing too hard, but only enough to smooth out the bumps. And also in a couple of places I have removed stain/oil back to original wood.
A similar thing happened when finishing the pedestal but I continued to finish the poly thinking it would cover it, but it is still viable. I think i can get away with it on the pedestal but not on the main surface of the table.
What is my best course of action here? If I sand back to wood to reapply oil where do I sand back to and how to sand back only the poly so to not remove all the stain? I know in an ideal world it would be take it right back and start again, but this table has a lot of layers/sections with moulding etc. I feel sanding too much will create a knock on effect and have to sand it all, which really isn't practical!
