Hi Fred,
you should be able to get a deeper blue on the ash grain. You could ask Dingobass to mix a deeper blue colour in the Bondi Blue kit and with more coats should deepen the blue stain.
Gav Turner on the forum used colortone dyes and got a nice deep blue STA-1 finish, see if you can find the build diary. It was GOTM about 6-9 months ago (guitar of the month). It is shown in the gallery section here check it out, scroll down bottom of page
