justallan, I've tried similar things in the past and the tips of the wire brush strands pushed some of the dirt and rust deeper in. This delaminated a larger proportion of the core: not a good outcome. Posting a few bucks to jay sounds more practical to me. However I must admit that long ago when I was young I used to spend many hours on doomed attempts to 'fix' broken car parts. Some of them worked for a while, but overall my record of success was woeful, and I usually fixed each two-dollar part several times before I weakened and bought a slightly better one from a wrecker. If somebody offered me the chance to be young again, I'd fall down laughing.
