Alloy wheels with corrosion blisters

I bought a 2006 Taco with 40,000 miles on it. The truck spent considerable time in Buffalo, NY and has developed corrosion under the paint on the aluminum alloy. I want to clean up this corrosion by chipping the silver paint, sanding and refinishing. Has anyone done this? Is there a "best way"? Also, what kind of refinishing paint should I use over the alloy?

Any help would be most appreciated.

 

My guess is that a wire brush or some scotchbrite pad is the way to go to get the stuff off....Leaning toward the wire brush....and then some sandpaper to smooth it out.
Prime and paint with any metal spray paint you'd like. I used Duplicolor sandable primer and regular Duplicolor paint for mine and I was pleased with the results.
