Hi Alkay, good to see you making some progress on this one.
Had a bit of a fail using black ink pad ink on my latest Tele build and would give that stuff a big swerve unless you want everything very, very black. It didn't want to dilute down and just soaked in really deep and then would not wash off? Seemed like it had a bit of an oily finish too which made the sand back to bare timber an even harder job. I should have spent the extra $5 on black fountain pen ink as I already know how that stuff works out and much easier to work with too.
