iron reconditioning

Let's be honest, everyone has or will have a shank at some point and most of us will have several... I have tried Eagle One Never Dull Polish, and while that didn't get rid of the scratches/marks, it did give my irons (2020 P770's) a great shine. Has anyone found anything that can remove...

Has anyone had their older irons reconditioned by a place like the Iron Factory or other? I have at two sets, '88 Redlines and '91 Staff FG-51's that I'd like to refurbish. Be great if anyone had pics and if the process really does result in "like new" clubs.
