Sure I used Stewart Macdonald stain, 1/20 dilution for the blue and Feast Watson Black 1/30 dilution.
I brushed on the blue first, using a fairly dryish brush, I rubbed it on newspaper after dipping in the stain to make sure it wasn't sopping wet
Let it dry and then rubbed it back, then stained with black the same way Click Here and rubbed back
Pre staining with blue made a big difference to the colour of the grain stripes, when I stained first with black, the grain showed black through the finish, Click Here staining blue first made the grain stripes a deep navy blue.
Then I stained blue again, this time using a soaking brush for the sidegrain and a blotted brush for the endgrain, also used Wez' suggestion of prewetting the endgrain to stop it drinking in the stain and getting darker.
When it was dry I used Rustin's Plastic Coating with a 1/30 dilution of the blue stain in it for 3 coats, then clear for the next 8 coats. Rustin's is a two pack finish, it is nice and viscous, it grain fills well itself so is terrific for ash, and it sets really hard. I brushed it on using a very fine bristle art brush, the coats went on smooth. A tip is to have two jam jars of lacquer thinners to wash your brush, rinse in one to get most of the lacquer off and then in the second to get it really clean, your brush won't clog up this way.
Then sanded the surface with 320, 400, 600, 800
1000, 1500, 2000 then used micro mesh pads up to 12000 you can see them in this link
This all let the grain show through nicely
And gives a lovely smooth and hard finish to the guitar that feels really great, especially on the neck, makes you want to rub your hand over the surface and whistle like a chippie.
Have fun with yours and post the pics to let everyone see how you are going Some day, I must put that 25th fret in.
