Disc Brake Squeal Fix .... Good, and Not So Good

I've had the pads off and sanded them, but no good.
On this week's MotorWeek, Pat Goss talked about a spray disc brake squeal fix, so whe I was riding today being very annoyed by that squealing, I stopped at an O'Reilly's I was passing and bought this:
www.oreillyauto.com/site/c/detail/PTX0/8...?keyword=anti-squeal
I sprayed it on right there in the parking lot. Rode the bike slowly and hit the brakes 8-10 times as the instructions recommended (I actually read them).
On the plus side, the squeal is gone. Totally and completely.
There is, though, one slight downside.
This shit is silver paint! I thought the silvering on the wheels and tires as I sprayed it was just the stuff making them wet, but when I got home, I noticed silver "paint", or whatever this stuff is, all over my hands.
I freaked, grabbed a rag, and started furiously rubbing on the wheels and tires. It partly came off the tires, but it didn't budge on the wheels!
I re-read the directions on the can, but it says nothing about this.
Does anyone know how to get this stuff off?

Some riders have used the silver anti seize on the back of the pucks to dampen the noise.

What is MEK?
Also, the directions say to spray it directly on the rotor.
Sigh .......
At least the brakes don't squeal anymore.

Be careful and use gloves outdoors, as most solvent fumes are easy to catch on fire.

Here is the manufactures technical sheet.
I don't know where you read to spray it on the "Rotor", it is normally applied to the rear side of the Pads.

FWIW - I fixed the window shattering Z1 squeal using some Ultra Black on the back of the pads. ....for now. I plan on trying to recreate those factory pads and shims.

Apparently, not clearly enough. :blink:
Tough lesson. Nothing ever gets sprayed on pads, and only high flash point/clean drying solvents on rotor.
Good luck.
