Thought I would do an update. I sanded the top of the pictured speaker above and reoiled it with Watco medium walnut. It turned out to match the color almost perfectly. (Although I would say the wood grain is a lot more defined and looks richer.
I am considering doing all sides to match. The original finish has a clear coat to protect it, what are everyone's thoughts on adding a clear coat after the watco? Any recommendations on products to use.
Also by the way I sanded with 200grt paper to take off the original finish and 400grt to make it super smooth and nice feeling. Im not sure if this is typical but the veneer is almost 1/8" thick and I didn't have to take off much to get down to the wood on the top.
