I just acquired a second set of Advent speakers, and the finish needs a little help. It's a warm walnut w/ low gloss but definitely more than just oil, maybe a varnish. The top of one has some black water stain (looks like a plant sat on top of it) and the bottom of the other had something on it that ate into the finish, and some adhesive like from old packing tape. On that one (the bottom) it was pretty bad, and I used a mild solvent and a fingernail to get rid of the adhesive; about half of it has the finish removed, and although a little of the color came up on the rags, the overall color is still pretty uniform.
So the question is, where to go from here? I'd like to avoid a complete refinish. I'm thinking about stripper to get rid of the finish on the two bad panels, but how easy is it to keep from going over the edge and messing up the side panels? Any chance of screwing up the veneer itself? Then on the top that has the black water marks, what will get rid of them? The veneer looks pretty thin.
For a new finish to match what's there, maybe Watco's natural Danish Oil?
Anybody have experience w/ restoring these speakers?
