Great find, thanks for posting!
The SPS was a pretty good coating overall, some really good attributes...graphene in it not. Dunno what graphene adds, if anything but could be a good choice for some regardless. I`m not so confident the Ethos will match it but only one way to find out; something seems a bit `off`. :shrug:
Feynlab folks are some smart guys, I believe them when they say something.
