Brake rotor "paint"? To stop brake squeal? Coat the friction surface of
brake pads with something, to stop brake squeal? I dunno about doing that.
I don't think that is good. Brakes are made to work as they come from the
manufacturer. Any magic Goo you put on them, especially where the friction
is 'supposed' to take place....that has to interfere with the stopping
power....They were designed to have maximum power---pad against rotor.
Period!
Maybe that aftermarket stuff you are putting between the pad and the
rotor....that stuff is what is causing your brakes to not stop you very
well, to heat up. Who knows what that stuff is? Why does that service tech
"know" better than the original engineers who were responsible for making
the best brake components possible?
You've said your brakes looked a little 'glazed' again....No wonder, you
put 'stuff' on the braking surface, and that stuff got ground and baked
right into the pads...
I never ever let anything touch either the pad surface or the rotors when
I am doing a brake pad replacement or a rotor replacement....and I did them
almost weekly on my 6-piston Brembo Big Red Porsche racecar brakes....The
only thing that ever got on the surfaces that were supposed to supply the
friction was brake part cleaner.....and then only if I'd made a mistake and
then I never really trusted that set of pads.....Clean! Clean!
The anti-squeal treatments I have seen are usually mechanical...some type
of dampner device that is clipped or clamped to the back side of the pads to
dampen vibrations and harmonics.
Geeze, on a vehicle with marginally adequate stopping power (if everything
is just perfect) putting some solution between the pad and the rotors...that
may just remove the "margin" and make the brakes...not quite adequate.
Not for me...I'd rather have squealing brakes than maybe run long at a
stop sign, rolling into a busy intersection at the bottom of a long grade or
something..
