  "summary": "Carbon-fibre shielding paint declared at 37 dB in one coat and 43 dB in two coats at 1 GHz, and up to 93 dB at 40 GHz, formulated for hardness and non-staining rather than for the highest attenuation per coat.",

      "Lower declared attenuation per coat than the same manufacturer's HSF54 and ECO54: the trade-off bought by the carbon-fibre binder is mechanical, not electromagnetic",
      "The 93 dB figure is at 40 GHz and says nothing about performance in the cellular and Wi-Fi bands most exposure comes from",
      "Must be grounded; an ungrounded conductive coating can increase the low-frequency electric field in the room",
      "Declared on flat samples, so seams, windows and penetrations are excluded from the number"
