I emailed BMF back in August after being more frustrated than usual with the newer BMF sheets I've gotten. Randy's response:
Hi Rich,
We have run into a supply chain issue with the chrome foil because of Covid. We are unable to obtain it at this time. We found a U.S.supplier able to provide foil. But they are unable to mill it any thinner than what we currently are using.
I am sorry for the disappointment this is causing. We are still trying to obtain the original foil.

I've since began using the matte aluminum BMF and while not ideal, and the sheets seem prone to wrinkling and creasing, I've gotten by. Let's all hope they work out their supply issues with the chrome sheets.
I've experimented with using thin, cheap foil (the stuff I tried was from Dollar Tree and you can't get much cheaper than that) and Microscale micro-metal foil adhesive. Results varied and I decided that as long as the matte BMF remains workable I'll stick with that. I will say that the Microscale adhesive did work the best for the few adhesives I tried. It didn't seem to leave much residue and what it did was easier to remove than the others. My problem was the adhesive tended to not cover evenly.
