Hey Tony,
While I have not applied this treatment to my fingerboards, there's a thread
here where some users have. You may want to PM them directly to ask the same question if they don't chime in here. It seems that tjclem has done it a few times, though others have as well.
You could also try the search function for "glue fingerboards" and get some hits. Of course, you'll get some that aren't helpful at all, but those are the breaks

.
Good luck!
