I saw this video and really wanted to try to replicate this without dropping a lot of money on gold ink I'll use 5 drops of and never use again.

I tried out 2 markers with some test decal paper from Dr Decal Mr Hyde.

EXPERIMENT #1: Sharpie & Signo vs. Water & Tru Oil

Applying ink: both go on, no problem.
Sharpie ink = more dull appearance, similar to Fender decals
Signo = a lot more yellow in the tint

(Wish I took a photo of this)

Leave to dry, but Signo is being slow and I'm impatient

Soak decal:
Sharpie - ink stays as is
Signo - ink goes haywire, but mostly only the spots that were thick/hadn't fully dried.

(Also no photo of this )

Allow decal to dry & apply TO over the top:
Sharpie - ink completely wipes off
Signo - not much change from original

Left = Sharpie permanent marker gold. Right = Signo gel pigment ink pen.

EXPERIMENT #2: Signo allowed to DRY vs. Water & Tru-Oil
This time I repeated with just signo but allowed to dry for hours before submerging.
Water: Ink messes up again
(Allow to dry)
Tru Oil: Looks like no change, but hard to tell...

This is after both steps:

Conclusion:
Sharpie is out because I can't TO over the top of it.
Signo - a possibility, but I'll have to apply it very carefully ON the guitar after the decal has dried. Leave it for AGES, hairdryer etc and pray it doesn't do something weird when I add TO.
Or just have a plain decal with no gold.

Thoughts people? Right now my neck's just sitting there waiting for some love (or more TO!)
