Wax does OK, but is not a very durable, protective finish. It seems that any penetrating finish such as lacquer or shellac darkens it too much. Is there a good finish that won't darken the alder much, or a sealer I can apply under lacquer or other finish to keep the color as light as possible?

You can also choose from any number of other sizings like thinned rabbit glue or a first generation wb varnish (remember hydrocote?). Fishing rod makers use the WB varnish as a color preservative over the decorative threads they wrap the rods with. http://www.mudhole.com/ThreadMaster-Col ... ead-Sealer . it looks a little like thinned down Elmer's glue which might also work well. What about rubbing the alder with pickling wash or wood bleach solution?
Next time use holly instead of alder. <g>
