Do NOT use disc brake quiet on the Thermoquiets. They have a built-in insulator. These pads MUST be installed dry.
Wagner Thermoquiet pads have a built-in insulator. It's essentially pad material that is molded onto a metal backing plate. These pads must be installed dry.
Here's some documentation from the Federal-Mogul Tech Center. Look on page 12:
http://www.centralpartsandsupply.com/specials_flyers/Brake noise & repair.pdf
"Wagner ThermoQuiet, with its patented IMI Sound Insulator design, requires that
NO chemical compounds (EMP, Silicone Lubricants, Moly Lube, etc.) be placed on the insulator area of the disc brake pads. ThermoQuiet with the IMI Insulator is designed to be installed right out of the box and onto the vehicle. Use of chemicals on the insulator may reduce the insulator’s effectiveness."

The Honda pads include Molykote77, which is a lubricant, not a disc-brake quiet type product. Honda wants it applied to both sides of the shims and on the backing plate.

It is okay to use a silicone/synthetic/moly-based brake grease on the back of most shimmed pads. Now, whether or not it is needed is up for debate. However, using
anything on the back of Wagner ThermoQuiet pads may cause problems.

One thing: when you add sauce to a pad, install it right away and mash the pedal before it dries. Let the parts seat metal to metal, not with a dried rubbery coating in between [it will eventually seat in, but is not good procedure]. Get both sides at the same time, and you won't pop a piston out when you mash the pedal.
As the Federal Mogul document states, it may cause the insulator to be less effective. On some pads with riveted shims, it may cause the shim to separate from the backing plate.
