Why not use some Blue Nugget Boot Polish to tie in with the neck?

Alternatively I was only thinking earlier today just how good an all over Tan or Darker Brown Boot Polish would look if I was ever to build a more natural looking beast, based purely on the great job you have done with that neck.

On each of the 3 basswood bodies I have built the necks were stained same colour as the Basswood body and Maple Neck as they were of a similar light shade and reckon if you did same colour toned boot polish it should come out pretty close. Always best to start out lighter as you can always go darker whereas the other way around usually ends up with lots of sanding back to try again.
