I have checked adhesion to PLA+ with Rustins and it adheres very well. I was very surprised by the conductivity which was around 20 Ohms for 35mm x 35mm surface area.
I would add that the graphene does transfer to your hands if you rub the surface, that does not mean however that the surface is flaky. I suspect a thin clear coat spray would solve that problem, it can also be over painted
I originally purchased it for the insides of a 3D printed case for the T41. At ?10 for a small tin it was worth the experiment.
There is a small Youtube video (Search Rustins G paint) showing a simple test for EMR suppression on a cardboard box, conducted by Rustins.
