I appreciate all of the feedback. I know very little about woodworking and wood finishes. The comment about water staining makes me wonder. I won’t know how deep it is until I start sanding and that seems like it could open quite a can of worms. Definitely plan to do both tops plates in their entirety to avoid mismatching finishes. The other top plate has some blemishes as well.

I have searched the web and Klipsch forum specifically but not finding a ton on Lacquer. I have some Walnut Lacquer K-horns with a bit of water staining and similar blemishes. It appears to be cosmetic/on the surface. A few questions; Assuming I need to sand with super fine grit to get the surface back to unblemished? What is recommended? Also assuming I would re-apply lacquer to restore the semi gloss finish? What specific product? I remember seeing something about a Valspar product. I do not have a sprayer so would need to apply by hand. Any insights appreciated.
