No, it would be silly to go back and rough it up. My point is that there is not any real advantage to finer sanding, and there could possibly be a disadvantage if taken to extreme. At the extreme where the wood is almost polished, there could be a slightly weaker bond between the seal coat and next coat. Treated correctly, even the polished surface should work well.
