This won’t be real helpful but yes back in the day when I was more adventurous I covered two small canvases with it and painted some botanicals over it with oils. The result seemed to work okay but I was too worried about it being non-archival and having to explain to a buyer if the results failed, so I ended up tossing those paintings. I understand the temptation to find workable substitutes for gold leaf. In the end I decided it was easier and safer to just do without.
