The first time you apply the brakes, it will scrape the paint off of all of the swept areas, leaving a perfect transition. The paint is thin enough that it won't harm your pads or anything else at all. The only thing is for the first 2-3 brake applications, your pads won't grip as well, but after that, its all good.

This method usually holds up at least two years without track use.
