If you don’t want to deal with the dremel stuff and getting your own graphite powder from pencil lead, check out YYF’s dark matter lube, it does a similar thing, though it’s not dry lube.
If you want true dry lube, try contacting Big Bang Bandalores on Instagram and ask for their Micronised Nano Lube. Its out of stock on their website but you may have some luck contacting them directly. It’s a carbon based dry lube. I have one bottle and it works great and is easy to apply, as there is a brush inside to apply it.
