I have tried that stuff a few times with mixed results. Some success (no
problems) to what a future glazed mess, (bouncy brakes in a few days). With
good pads and rotors and a little break in care just not needed.

Yeah, I've heard of the spray on the rotor stuff. I think some are aluminum
based. Supposedly does not reduce braking effectiveness.
Other companies make pads that leave a coating on the rotor. I think its
called "TFT", transfer film technology.
