Joe,
Sandblasting old chrome off is not a good idea if you plan to rechrome the part or frame. Etching will occur in your case where chrome comes off partially. A plater can chemically strip the old chrome and ready it for repolishing; if they know how to work on bike frames.

Refurbishing an old Columbus SL frame and bead blasting is not removing all of the old chrome . Some of it is flaking and blowing off as it is being blasted but there is good portion that is not . Does any one know how a practical way a home owner can remove the old chrome that can't be blasted off with a bead blaster ? Or better yet how does a professional pant shop do remove it ?
