I gave this stuff a try yesterday so we'll see how well it works. The stock Brembo pads dust something insane so I should know if it's actually making a difference within a few days. I plan to use it on the WRX soon too since her Girodisc Magics pads are also very dusty. The can is a lot smaller than I anticipated, but I figure it should be good for 2-3 applications, maybe more if used with a bit more moderation. I made sure to get it all over my calipers too. I'll have to be pretty good to command the $8-9 price, but for free after rebate it's worth a shot.
