Graphite paint has a high enough sheet resistance that eddy currents will not be significant.
Sheet resistance is specified in ohms per square, because if one makes a square of some sheet, with low resistance connections on two opposite (and parallel) sides, the resistance does not depend on the size of the square.
Nickel powder paint has a sheet resistance of about an ohm per square. Silver powder paint is about a tenth of an ohm per square, and graphite paint is tens to hundreds of ohms per square. Metals are hundredeths to thousandths of an ohm per square, for foils and thin sheets.
