Hi Dave. Just saw this post. I used a very diluted Feast Weston Japan Black wash on my TL-1Q (diluted with turps or metho...can't remember), wiped off the excess and repeated as necessary. I then added the colour burst (diluted with water). I only sanded it back with a kitchen nylon scourer to remove the raised grain.
I did a fair bit of testing on scrap first (highly recommended!!!). Not sure how it will work with the gold but I hope this helps.
