Thanks for getting back Lawrence, Letts and Al - i'd spent more time watching my inbox than watching this thread, so only saw this today.
What sort of thinner should I add to the Rustins? - and do I add this once the Rustins has been mixed with the hardner that came with it? Also, how many coats of Rustins did you put on?
I'm not too precious about the outcome of this, just tidying up what's already there really. In some ways this is pretty much my "test neck" - as i wouldn't attempt this on a more valuable bass!
One thing i should've stated earlier is that I had to do a bit of a filling job on part of the board. Some pratt who used to own the bass decided to do a Billy Sheehan-esque scalloping job on some of the frets up the dusty end - so I've filled these in with wood filler and sanded the board with a radius block so the filled sections are now flush with the board and it's all neat and smooth
Only problem is, the colour of the filler stands out like a sore thumb! This is partly why I was originally asking about darkening the board before the Rustins went on - I wanted to try and mask the filled sections somehow
If they can't be masked, I can live with it
