Thanks Bartamos, I have been using a wire wheel for 30 years and always been happy with the results. That said, I also don't want to keep doing the same old thing just because that is what I have always done.
That rust reformer does look like a final step. Like you said, I will get it as bare as I can before I put it on.
My intention is to strip/paint it, then put a heat shield in and get one of the LMC poly floormats for it.
