Sorry, zandit, just saw your post now.
I was trying DT final coat over a waterbased ink stain. It just never did anything no matter how many coats I put on. DB said that the final coat wont work very well unless applied over either the stain coat or both stain and intensifier coats or another oil based sealer.
I can see that you have used the the British Paints Interior stain which is an oil based stain (isn't it?) and you have filled the timber with ebony timbermate (nice choice). I must say i've never tried to put DT over a different stain. my only worry being that the BP stain would have some solvents in it for drying which may play hovoc with the DT.
If it were me....and only because I'm a sucker for taking forever to do my builds....I'd consider sanding the BP stain off, re-timbermating the mahogany and starting the DT from scratch. Gives you more time to talk to your build.
If you are not keen on that idea, post the question on DB's Corner and see what he says. or whack down a coat of your black stump on it and see how crazy it gets! if it doesn't work you can always go back to the drawing board (nothing that can't be undone there!).
A word of advice on the Black Stump. When you first apply the stain coat you may not think its very dark, don't be disheartened, after about 4 stain coats and 3 intensifiers it gets pretty black (even on a maple neck). If you want to see what its like check out AndrewA's PBG build or my
