Yeah, I had the same breakthrough last month. Thinning the adhesive just a bit more than the instructions said made all the difference for me. Suddenly the gold leaf just laid down perfectly.
Man, I know exactly what you mean. I tried thinning the glue with a little water and alcohol mix, and suddenly the gold leaf went on smooth. Before that, it was always a fight to get it flat. So glad you figured it out, it's a game changer.
