Even more labor intensive, I used Techline's thermal dispersant coating on the Healey's rotor hat and edges (plus rear drums).
Surface must be blasted and cleaned with solvent; mask off all areas that are to remain uncoated; use airbrush to apply a ridiculusly thin amount (like .0015"); cure in an oven at 300 degrees (part temp) for an hour.
And you call yourself an enthusiast!
