A very long time ago, I worked in a shop where the practice was to spray a thick coat of Permatex High Tack on the back of brake pads to keep brakes pads from squeaking.
These days, I'm running Hawk DTC-30 track pads on my street/track Miata. They're effective, but they're also very noisy. Is there a modern anti-squeak goo that can survive a few track days a year?
We used to just put anti seize on the back of the pads.
Street pads tend to squeak due to backing-plate-on-caliper movement, race pads tend to squeak due to normal pad-on-disc action. You could try some anti-seize but I doubt anything you put on the back of the pad will help.

THIS.
Loud brakes save lives.
I've used the Permatex anti-squeal spray on my RX-8 with Hawk HP+ pads. While it helped on the street, it does not survive track sessions.
Track pads have a tendency to squeak/squeal when cold and goes away when warmed up.
Goo of what ever won't do much.
Go to a less agressive pads. A Miata will get by on Hawk HP+ pads. Some say they squeak, mine never did.
A little wd-40 on the rotor would do wonders.
NOTE: please do not put wd40 on your rotors.

Use Bacon Fat, it smells better when it (eventually) heats up.

Noisy brakes are a sign of being awesome.
Anti noise spray is mostly a kind of resonance abatement between the pads and calipers. Greasing the backside of the pads (never use antisieze on anything remotely near the brakes, brake heat turns it to a spiteful paste, plus antisieze on brake parts/hubs/lug studs is one of the Warning Signs that a complete hack has worked on the car and you must be cautious) is mostly a forestalling of "gritching" on application as the caliper flexes around the pad, but it is not going to stop squeal, which is a very high frequency harmonic generated in the pad itself.

This ... !!!
I still use the Permatex stuff on street brake jobs. Sometimes they squeal...sometimes they don't. I'm not sure it does anything, actually.
I've never used spray stuff, but the tacky red ooze (CRC Disc brake quiet) product worked wonders on some aggressive compound pads in Wilwood Dynalites or Dynapros. They squealed like mad before, but after red goo never made a peep again. No track events to test against, but lots of aggressive braking and heat cycles over the life of the pad. The red goo was still on there when I changed the pads. Obviously some noise is from the pad-disc interface, and this stuff won't help.
