Batch replacing folder icons in Snow Leopard

I changed a number of my folder icons using the Get Info, copy, paste method. Now I want to change them back to the default blue folder. I started copying and pasting the generic blue folder one by one, but is there an easier way to change a bunch of folders at once? In OSX 10.5, I used to be able to select 10 or more folders and have one "Get Info" window pop up where all the icons can be changed, but that doesn't work now with Snow Leopard.

I have tried Candy Bar, and I have tried the method here: http://www.usingmac.com/2008/2/2/leopard-change-default-icon, but the existing folder icons do not change -- only new folders show the new icon. With Candy Bar some of the existing icons change but the bulk of them don't.
